Bone marrow is a semi-strong tissue found inside the light or chancellors parts of bones. In birds and well evolved creatures, bone marrow is the essential site of fresh blood cell creation or haematopoiesis. It is made out of hematopoietic cells, marrow fat tissue, and steady stromal cells. In grown-up people, bone marrow is fundamentally situated in the ribs, vertebrae, sternum, and bones of the pelvis. Bone marrow includes roughly % of complete weight in sound grown-up people, to such an extent that a man gauging kg ( lbs) will have around . kg ( lbs) of bone marrow.

A sarcoma is a threatening tumor, a sort of disease that emerges from changed cells of mesenchyme (connective tissue) origin. Connective tissue is an expansive term that incorporates bone, ligament, fat, vascular, or hematopoietic tissues, and sarcomas can emerge in any of these kinds of tissues. Sub-sequently, there are numerous subtypes of sarcoma, which are arranged dependent on the particular tissue and kind of cell from which the tumor originates. Sarcomas are essential connective tissue tumors, implying that they emerge in connective tissues. This is as opposed to optional (or "metastatic") connective tissue tumors, which happen when a malignant growth from somewhere else in the body (like the lungs, bosom tissue or prostate) spreads to the connective tissue. Causes and danger factors.

Carcinomas are normally organized with Roman numerals. In many arrangements, Stage I and Stage II carcinomas are affirmed when the tumour has been discovered to be little or potentially to have spread to nearby constructions as it were. Stage III carcinomas regularly have been found to have spread to provincial lymph hubs, tissues, or potentially organ structures, while Stage IV tumours have effectively metastasized through the blood too far off destinations, tissues, or organs. Carcinoma is a threat that creates from epithelial cells. In particular, a carcinoma is a malignancy that starts in a tissue that lines the inward or external surfaces of the body, and that emerges from cells beginning in the endodermal, mesodermal or ectodermal germ layer during embryogenesis.

Chemotherapy (frequently shortened to chemo and now and then CTX or CTx) is a sort of malignant growth therapy that utilizes at least one enemy of disease drugs (chemotherapeutic specialists) as a component of a normalized chemotherapy routine. Chemotherapy might be given with a corrective plan (which quite often includes mixes of medications), or it might intend to drag out life or to decrease manifestations (palliative chemotherapy). Chemotherapy is one of the significant classifications of the clinical order explicitly gave to pharmacotherapy for malignancy, which is called clinical oncology.

n assessing the quality of health services, the use of quality and resolution indicators used in the operating room stands out. The cancellation fee for operating procedures is one of the most important. Cancellations interfere with the outcome of care and increase hospital costs. In the case of cancer patients, the consequences are severe, since early surgical intervention directly influences prognosis, reducing morbidity, and mortality. Considering that surgical suspensions should be prevented, pre-anesthetic consultation and telephone confirmation days before the procedure configure strategies that can be adopted to minimize the problem. A descriptive observational study with a quantitative approach was conducted on the impact of previous telephone confirmation on the reduction of cancellation of oncologic surgeries due to absenteeism. The research was carried out at Professor Alberto Antunes University Hospital, Federal University of Alagoas (HUPAA/UFAL), city of Maceió, State of Alagoas, Northeastern Brazil. The sample consisted of 205 patients with scheduled cancer surgery from January to June 2019, after approval by the Institutional Ethics Committee. Data analysis was performed descriptively. The effectiveness of previous telephone confirmation was verified, with a 50% reduction in cancellation of elective oncologic surgeries due to absenteeism. The implementation of a call center to confirm the presence of the user consisted of an impact strategy in reducing the cancellation of previously scheduled cancer surgeries.

Over the past century, Hodgkin's Lymphoma (HL) has gone from a uniformly fatal disease to a curable disease in approximately 75% of patients worldwide. The selection of therapy should balance the desire to maintain a high rate of cure with the need to minimize long-term complications. In this retrospective study, we propose to report the experience of the management of this pathology to the National Institute of Oncology (INO) in Rabat. We recorded and collected data from 152 patients admitted to the National Institute of Oncology for MDH, the average age is 36.2 +/-16.3 years with extremes of 17 and 81 years. Men made up 52%?? of the total population. The favourable localized stages (IA, IIA) represented 20.4%, we did not have enough data to classify 7 patients. ABVD (Doxorubicin, Bleomycin, Vinblastine, Dacarbazine) was the 1st line protocol in 66% of patients, BEACOPP standard 13.4% (Bleomycin, Etoposide, Doxorubicin, Cyclophosphamide, Vincristine, Procarbazine, Prednisone); some have BEACOPPP had the switcher protocol to the BEACOPP standard after 3 cures). 55.9% of patients received between 3 and 6 courses, 17.8% between 7 and 8 courses.
27.2% of patients had curative adjuvant radiotherapy using the irradiation technique (IFRT) Field concerned Radiotherapy with doses of 20 Gy and 30 Gy depending on the response to the initial medical treatment and the initial stage. The median overall survival for all stages was 72.9% after 84 months of follow-up. All-stage event-free survival was 69.3%. The over hall survival according to the favourable localized stages (IA and IIA) was 75.1% higher than that of the unfavourable stages of 71.5% (p=0.186). Patients who had adjuvant radio therapy had overall survival (72.4%) and those who had not been irradiated 72.1% (p=0.733). All-stage event-free survival was 65.1% after 84 months follow-up 95% CI (62.2%-67.9%). Hodgkin lymphoma is a curable malignant tumor in the early and late stages. The treatment should be refined on prognostic models.

Resveratrol (trans-3,4’,5-trihydroxystilbene) is a naturally occurring
antifungal found in a variety of foods including the skin of red grapes and
peanuts. Since the seminal report that resveratrol could inhibit multiple
stages of carcinogenesis, it has been the subject of extensive preclinical
investigations for the treatment and prevention of numerous pathologies
including cancer, cardiovascular and Alzheimer’s disease, insulin resistance,
and diabetes . Attempts to translate these findings to humans have increased
in recent years but there are still fundamental gaps in our understanding of
the pharmacokinetic pharmacodynamic relations and how plasma/target tissue
concentrations correlate with clinical efficacy or beneficial effects on health
maintenance . Such information is needed to inform the choice of optimum
dose and formulation requirements, and to enhance understanding of the key
modes of action for resveratrol in each pathology it is also particularly important
given the notoriously low systemic bioavailability of parent resveratrol due to
its rapid metabolism, which, if not taken into consideration, would affect its
clinical utility.

Pancreatic cancer arises when cells in the pancreas, a glandular organ
behind the stomach, begin to multiply out of control and form a mass.
These cancerous cells have the ability to invade other parts of the body. A
number of types of pancreatic cancer are known.

Male breast cancer (MBC) is rare, accounting for less than 1% of all breast cancer and less than 1% of all cancer cases, with less than 0.5% of all cancer deaths in men, annually.MBC usually presents as a firm, painless mass along with palpable axillary nodes, nipple retraction, and ulceration of the skin at presentation. MBC is usually located in the subareolar region, but can also be seen in the upper outer quadrant. As is the case with women, the left breast is involved more predominantly than the right breast, and approximately 1% all of cases are bilateral. Approximately 90% of MBC are invasive ductal carcinomas. Lobular histology is rare, accounting for only 1.5% of MBC. MBC has high rates of hormone-receptor expression; approximately 90% express oestrogen receptor (ER), and 81% express progesterone receptor (PR).

Drug-induced predisposition to acute renal failure (ARF) is a facet of nephrotoxicity hitherto mostly uncharacterized, quite underestimated, and impossible to diagnose, which potentially has a high human and socioeconomic impact. Our study has identified urinary GM2AP as the first of a new class of biomarkers of the enhanced risk of suffering an acute renal failure after a subnephrotoxic treatment with gentamicin. Gentamicin-predisposed animals with no sign of renal cancer develop ARF when exposed to a second potentially nephrotoxic drug, also given at subnephrotoxic doses that are harmless to non-predisposed individuals. Subnephrotoxic gentamicin did not alter renal GM2AP gene expression or protein levels, determined by RT-PCR and Western blot and immunostaining, respectively, nor was its serum level modified. Further experiments indicate that, likely, the origin of the increased level of GM2AP in the urine might be a defective tubular handling of this protein as a consequence of gentamicin action.

Breast cancer is cancer that develops from breast tissue. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or yellow skin.

Tracheal cancer is a rare neoplasm that accounts for only about 0.1% of all respiratory tract tumors. Cystic adenoid carcinoma (or cylindroma) represents the second histological type of tracheal tumors in order of frequency. These lesions are characterized by slow local growth, perineural invasion, and potential local and distant recurrence. Complete surgical resection offers the patient a better opportunity of prolonged survival or complete remission. The addition of photon- or electron-beam radiation seems to influence local control but does not affect survival. In this paper, we report a clinical case describing the characteristics and management of adenoid cystic carcinoma of the trachea in 59 years-old men.

Background: Rhabdomyosarcoma (RMS) is the most common soft tissue tumor in childhood with a cure rate of 70% in localized disease. We aimed to study the prognostic factors of non-metastatic RMS in Tunisian paediatric patients.
Methods: We reviewed data of children aged <18 years, treated in the Salah Azaiez Institute for a localized RMS during 20 years. Prognostic factors were studied and survival data analysed.
Results: 75 patients were included. Mean follow up was 30 months. The 5-year OS and DFS were 50% and 26%, respectively. By univariate analysis, DFS was significantly correlated to chemotherapy, radiotherapy (RT) and post-surgical RT with p 0.02, 0.003 and 0.01, respectively. The surgery failed to be a significant factor. We didn`t find any factor with a significant relationship with DFS in multivariate analysis. By univariate analysis, 5-year OS was significantly and adversely influenced by 4 factors: tumour size>4 cm, non-alveolar RMS, positive regional nodes and para-meningeal location, with p: 0.050, 0.05, 0.04 and 0.04, respectively. RT and postsurgical RT were associated with a good prognosis in OS p=0.009 and 0.05, respectively. Age, histology, primary site and IRS group failed to be significant. By multivariate analysis, OS was strongly correlated to radiotherapy p=0.03, Odds Ratio (OR) 3.1, confidence interval (IC) 95% [1.05-9.3] and para-meningeal site p=0.04, (OR) 0.3, confidence interval (IC) 95% [0.1-0.9].
Conclusions: Compared to the literature, we noticed that the prognosis of our patients was worse so we should improve it by making the treatment more personalized and encouraging research.

Introduction: Breast cancer is the most common cause of cancer in women in India. India ranks number one in the number of healthy life years lost (DALY- Disability Adjusted Life Years ) due to breast cancer. Surgery, radiation therapy and chemotherapy (+/- hormonal therapy) constitute the multimodality approach for treatment of breast cancer. Radiation therapy is recommended as a treatment of choice for post-operative ca breast patients. Radiation doses to nearby critical normal structures like heart, lungs, and contralateral breast (CLB) increases risk of second malignancies due to increasing life expectancy of the patient. During external beam therapy unwanted radiations produced due to leakage from collimator and scatter from primary beam . It appears prudent to be aware of these potential risk and efforts must be made to maintain a dose to CLB as low as reasonably achievable. In this study, we measured doses to the CLB and studied reduction in dose achieved by use of of a 2mm lead shield. Materials and Methods: Ten number of post-operative Ca-Breast patients were taken for our study. All the patients underwent 3D conformal radiotherapy in Linear Accelerator(Make: Varian Medical Systems, Model: Clinac 2100CD) which has multi leaf collimator 40 pairs. Forward IMRT Treatment plans were performed in Eclipse Treatment planning system (Make: Varian Medical Systems, Version 13.8)As the intent is to measure the contralateral breast dose the TLD discs ( Type; CaSo4;Dy, 13mm dia, 0.8mm thick) were placed over the CB; Customized lead shields were prepared to study the reduction of dose to CB. Measurements were made with the TLD Discs with the presence and the absence of customized lead shield over the CB and doses were calculated with the help of TLD Reader (Make: Nucleonix, Hyderabad). Here we present a case of 10 ca breast patients who received radiotherapy post operatively. Radiation therapy of 40.05 Gy was planned in 15 fractions, 5 days a week, using the Eclipse Treatment Planning System version 8.9.15, with a pencil beam convolution algorithm and 6 MV photon beam. Plans were transferred to a linear accelerator (Varian 2300 CD) for execution of treatment. Twenty-four CaSO4 thermoluminescent dosimeter discs (TLDs) were used for dose measurement over the CLB. The dose was measured for each patient without a lead shield for 7 fractions and with lead shield for 7 fractions. Results: Mean doses/fractions received by the CLB without and with a lead shield were 12.62 ± 1.29 cGy and 6.42 ± 2.62 cGy, respectively, with total doses of 208.326 ± 32.43 cGy (5.14% of prescribed dose) and 113.7 ± 65.62 cGy (2.83% of prescribed dose). The average reduction in mean dose with a 2mm thick lead shield was 53.10 ± 17.18%, in the range of 20 to 80% and statistically significant (p < 0.001) Conclusion: The above study was performed for 10 number of cases and it was evident in all the patients the dose to CB has reduced to less than 50% (p value <0.05). The lead sheets were customized for individual patients and it was an effective parameter in CB dose reduction. The lead sheets are in- house customized and can be easily made in every department with minimal cost. This study will be further extended for more number of cases with increment in lead thickness. We may find an optimum lead thickness that reduces significant dose to CB without creating discomfort to the patients.

Background: Most of patient with Biliary Tract Cancer (BTC) has not access to surgery because of Advanced/metastatic disease at diagnosis (aBTC). They receive palliative chemotherapy and/or Palliative Care (PC). We studied if early palliative care referral might influence Overall Survival (OS) and the aggressiveness of end-of-life care.
Participants: We conducted a retrospective multicentric cohort study in patients with non-curative BTC, diagnosed between 2013 and 2019 in 6 hospitals of Eastern France. PC was defined a specialist-delivered palliative care encounter.
Results: 200 patients with aBTC were included. 87 (44%) never received PC, 30 (15%) had very early PC (<3 months after aBTC diagnosis), 20 (10%) had an early PC (3-6 months), and 63 (32%) had late PC (>6 months). The median time between referral and death was 0.9 to 1.3 months. OS were 12.4 months (no PC), 3.0 months (PC<3 m), 6.4 months (PC 3-6 m), 16 months (PC>6 m). There was no evidence for survival improvement with early PC. PC tended to reduce chemotherapy near death (37% without PC, 30% with PC<3m, 11% with PC 3-6m, 10% with PC>6m), visits in emergency department (ED) during final month (respectively: 36%, 20 %, 15%, and 7%), intensive care unit hospitalizations (ICU) near death (13%, 0%, 0%, 2%). Place of death seemed to be positively impacted by PC (conventional acute unit, respectively: 73%, 21%, 21%, 25% and ICU or ED: 8%, 0%, 5%, 2%).
Conclusion: Referral to PC remains too late in the support of patients with aBTC. Our practice should evolve: all patients with aBTC should be referred to early PC in palliative care unit after diagnosis to improve the management of end-of-life, symptoms, and family needs.

Purpose: The purpose of this study was to analyse the clinical management and Quality of Life (QoL) of frail patients with cancer, chronic background pain and Breakthrough Cancer Pain (BTcP) and to assess whether treatment was conditioned by their frailty status.
Methods: This was an observational study in adult frail patients with cancer, chronic background pain and BTcP. Outcomes of interest collected include clinical and sociodemographic data, Karnofsky Performance Status, quality of life (EuroQoL-5D-5L), chronic pain and BTcP characteristics, as well as treatments administered for their control.
Results: A total of 222 patients were included with a mean age of 68 years (range 24-91), 60.5% men, with a mean Karnofsky of 63.2%. The number of daily episodes of BTcP was 3.8 (95% CI 3.3-4.3), with a duration of 34.6 minutes (95% CI 28.8-40.3), and 56.8% had a gradual onset. Opioids were administered to 88.3% of patients for the chronic pain, and to 83.8% for BTcP. The treatment's daily doses administered for chronic pain and BTcP did not differ from those usually recommended. QoL was significantly worst in frail patients with cancer than EuroQol-5D-5L healthy age-matched no frail patients and was related to performance status (p<0.001) and to the social-familial status (p=0.045).
Conclusion: BTP in frail patients with cancer presents with more episodes, of a shorter duration and more gradual onset compared to other published references of patients with BTcP. QoL was seriously affected in this group of patients. No relevant differences were seen in the doses or method of administration of treatments for chronic pain and BTP in frail patients with cancer as compared to the standard recommendations for non-frail patients. Our findings support the importance of the frailty assessment in all patients with BTcP.

Objective: The aim of the study was to determine the nationwide prevalence, trends, and predictors of inpatient PCa screening in average risk patients using the National Inpatient Sample (NIS) database.
Methods: NIS records from 2006 to 2014 were used to evaluate inpatient PCa screening encounters across United States (US) hospitals. All male patients between the ages of 45 and 69 at average risk for PCa were included. The outcome was whether a patient had an encounter for PCa as noted on their discharge record. Variables analyzed included demographic factors, hospital characteristics, and other concomitant diagnoses for prostatic or urologic problems.
Results: The prevalence of inpatient PCa screening was 2.57 per 100,000 hospital discharges. In a multivariate setting, the following were significant factors associated with greater odds of inpatient screening: Medicare (AOR: 3.07; P=0.0016), self-pay or uninsured patients (AOR: 1.74; P=0.0371), rural (AOR: 11.9; P ≤ 0.0001) or urban nonteaching hospitals (AOR: 5.26; P ≤ 0.0001), Midwest hospitals (AOR: 4.90; P ≤ 0.0001), urinary tract infection (P=0.0367), genitourinary symptoms (P<0.0001), prostatic hyperplasia (P=0.0006), or other male genital disorder diagnoses (P<0.0001).
Conclusion: In light of unequal access to healthcare, disparities exist in uninsured and rural populations regarding cancer screening. PSA is a minimally invasive test that can help screen individuals at increased risk for the development of prostate cancer, allowing for early detection, prevention, improved rates of cure and ultimately, decreased rates of mortality.

Standard of care and protocols for the treatment of pediatric cancer lead to a clear improvement in survival rates and quality of life. Little is known about how these treatments are implemented in Brazil. Our study aimed to evaluate children treated for Hodgkin Disease (HD) in south Brazil between 2002 and 2013 through the analysis of medical records in 6 different centers.
Fifty-nine children and adolescents were included. The median age was 12 years (range 3-18 years). Male:Female ratio was 1.95:1. Localized disease (stage I/II) was observed in 30 patients (50.8%) while the remaining 29 (49.2%) had advanced disease (Stage III/IV).
The chemotherapeutic treatment schema was different among services and comprised three different based protocols. ABVD schema was the most frequently used (52 children (88.1%). The number of cycles was highly variable (4-16 cycles) even at the same clinical stage and with similar clinical response.
These data highlight the importance of turning the “best practice policies” readily available to all pediatric oncologists. Local protocols allow integrative studies among centers that would certainly maintain or improve cure rates, reduce long-term toxicity and evaluate specific biological characteristics of these diseases in our population.

Introduction: Metastatic Merkel Cell Carcinoma (MCC) is characterized by poor prognosis and poor response to cytotoxic chemotherapy. Immune Checkpoint Inhibitors (ICIs) were evaluated in several clinical trials, providing interesting results in terms of activity and efficacy, with a generally manageable safety profile. Limited data are available for use of ICIs in patients affected by multiple chronic diseases. We present the case of a patient with several comorbidities treated with Avelumab for advanced MCC, who developed a durable complete response.
Case description: A 78-year-old woman with several chronic diseases was treated with Avelumab for MCC with lung and subcutaneous metastases, developing radiological complete response after 5 cycles. Treatment was well tolerated and no severe adverse events were observed.
Conclusion: Our case shows that Avelumab is an active and safe treatment in multimorbid patients with advanced MCC. More consistent data from randomized clinical trials are needed to confirm these results in a large patient population presenting these special features.

Breast Cancer (BC) is the most common cancer in women accounting for about 30% of all female cancers. The average age of incidence varies among countries. While it is 62 years in the US, it is 48 years in the Arab countries. According to a recent statistics done on well studied charts of consecutive one thousand operations on breast cancer patients done by me in Syria, 20% of cases occurred below the age of 40 (vs. 8% in the US). This has an important implication.

Objective: Malignant Pleural Mesothelioma (MPM), a locally invasive tumor, is treated with a combination of surgical, radiation, and medical therapies, but the treatment efficacy remains insufficient. Gene therapy for MPM has been attempted to improve the prognosis of the disease, but has not yet reached a practical level. One of the barriers to MPM gene therapy is the resistance of MPM cells to transgene expression. Therefore, the purpose of this study was to find techniques to achieve high-level transgene expression in MPM cells resistant to transgene expression.
Methods: We evaluated two MPM cell lines, NCI-H28 (H28) and NCI-H2052 (H2052), for their resistance to transgene expression, and then examined whether transgene expression in the resistant H2052 cells was enhanced by treating the cells with D-glucose, an extracellular signalregulated kinase 1/2 inhibitor LY3214996 (LY), and a histone deacetylase inhibitor trichostatin A (TSA), which have been reported to increase transgene expression. Cellular transgene expression was evaluated by a reporter gene assay in which a human cytomegalovirus immediate early (CMV) promoter-controlled Enhanced Green Fluorescent Protein (EGFP) gene was inserted into the cells using a human adenovirus (ADV) vector. The extent of EGFP gene expression was examined by fluorometric assay, fluorescence microscopy, and EGFP quantification by ELISA.
Results: The fluorescence intensity in H2052 cells was only 13.9% of that in H28 cells. D-glucose treatment of H2052 cells after transduction (posttreatment) increased the fluorescence intensity in H2052 cells by only 1.9-fold. LY treatment of H2052 cells before transduction (pretreatment) increased the fluorescence intensity in the cells by only 1.7-fold. TSA pretreatment increased the fluorescence intensity in H2052 cells by as much as 6.9-fold, to almost the same level as that in H28 cells. When the TSA-pretreated H2052 cells were posttreated with D-glucose, the fluorescence intensity in H2052 cells was enhanced to 400% of that in H28 cells. The elevated EGFP gene expression by the joint effect of TSA and D-glucose was also confirmed by fluorescence microscopy and EGFP quantification by ELISA.
Conclusion: It was suggested that TSA pretreatment could remove the resistance to transgene expression of MPM cells and the joint effect of TSA and D-glucose could highly enhance transgene expression in the resistant MPM cells.
