Bevacizumab, an anti-angiogenic agent targeting vascular endothelial growth factor (VEGF), is widely used for the treatment of ovarian cancer. However, no predictive biomarkers of clinical outcome for bevacizumab therapy have been identified. Adipose tissue secretes various growth factors, including VEGF, which may neutralize bevacizumab and attenuate its effects. Therefore, we evaluated whether obesity is a predictive biomarker of clinical outcome in ovarian cancer patients treated with single-agent bevacizumab.

Thirty patients with recurrent ovarian cancer treated with single-agent bevacizumab were studied. Body mass index (BMI) and visceral fat area (VFA) were measured to assess the presence of obesity. VFA was measured using computed tomography volume-analyzing software. The association of BMI and VFA with clinical outcomes were evaluated.

High BMI and high VFA were significantly correlated with progressive disease (p=0.0195 and p=0.0352, respectively). A significant correlation was identified between high BMI and progressive disease in multivariate analysis (p=0.0459). Furthermore, there was a trend toward shorter progression-free survival and a significant shortening of overall survival in high-BMI patients compared with low-BMI patients (p=0.101 and p=0.0417, respectively).

This study demonstrated that obesity is a predictive biomarker of poor benefit from single-agent bevacizumab therapy in recurrent ovarian cancer patients. Obesity may be a useful benchmark for the administration of bevacizumab in daily clinical practice.

Complete cytoreduction has been established as the most significant factor of long-term survival in epithelial ovarian cancer. Perioperative intraperitoneal chemotherapy has been added in the treatment of ovarian cancer the last 20 years. The purpose of the study was to determine the outcome of women with ovarian cancer using the data of one surgical team.

Women with ovarian cancer treated from 2000 to 2019 by the same surgical team were enrolled in the study. The patients underwent cytoreductive surgery combined with perioperative intraperitoneal chemotherapy. Clinical and histopathological variables were correlated to hospital mortality, morbidity, survival and recurrences.

The mean age of 350 women was 59.5+11.7 years. The hospital mortality and morbidity rate were 2.0% and 28.3%, respectively. Complete cytoreduction was possible in 60% of the cases. The overall 5- and 10-year survival rate was 47% and 39%, respectively. click here The prognostic variables of survival were the extent of peritoneal malignancy, the extent of previous surgery, the grade of differentiation, the use of adjuvant chemotherapy, the lymphadenectomy of the resected large bowel, and the postoperative morbidity. The recurrence rate was 45.7%. The extent of peritoneal carcinomatosis, the extent of previous surgery, and the grade of differentiation were the prognostic variables of recurrence.

The limited extent of peritoneal carcinomatosis in women with well differentiated ovarian cancer that do not have history of previous surgery, who undergo standard pelvic peritonectomy procedure, and receive adjuvant chemotherapy are expected to be long-term survivors.

Postoperative chyle leak, termed 'chylous ascites', is a rare complication with a reported frequency of only one in 20464 abdominal operations. The purpose of this study was to summarize the available scientific data reviewing the most relevant studies for this type of postoperative complication after pancreatic surgery, highlighting at the same time the necessity for pancreatic surgeons to retain a high level of clinical suspicion for the early diagnosis and its therapeutic management.

A thorough literature search in Pubmed and Google Scholar, under the terms' chylous ascites OR chyle leak AND pancreas OR pancreatic', since the year of inception until 19th of February 2021 was conducted by the authors and the associated results are presented in this narrative review.

Chyle leak is a rare complication following pancreatic surgery. Patients may suffer from exudative enteropathy and malnutrition leading to repeated infections and impaired wound healing or even death secondary to sepsis. Several studies ha far as hospital stay or survival are concerned. Researchers found that patients with diffuse chyle leak tended to have a worse 3-year survival rate (18.8%), which can be attributed to postoperative complications and early demise due to immunosuppression associated with the leak, or delayed adjuvant chemotherapy Conclusion Further clinical research is needed to enhance prevention, diagnosis, treatment and long-term prognosis of this relevant surgical problem that shows trends of increase due to the great number of major operations which are performed nowadays.
We aim to review the available literature on surgical management of oligometastatic pancreatic ductal adenocarcinoma (PDAC), in order to assess the clinical outcomes and intraoperative parameters of the different strategies.

A systematic literature search was performed in PubMed database, in accordance with the PRISMA guidelines. Nine studies met the inclusion criteria incorporating 401 patients.

Perioperative mortality was as low as 0%, regarding resection of pancreatic cancer combined with synchronous metastasectomy.

Currently, postoperative overall survival and progression-free survival have increased compared to previous trials. Nevertheless, the lack of precise operative indications delays the enhancement of survival rates. Well-designed, randomized controlled studies, assessing pancreatic surgery combined with metastasectomy, are necessary to further assess their clinical outcomes.

In lymphedema the lymphatic stasis causes an inflammatory reaction that leads to the proliferation of adipose tissue and fibrosis, resulting in mild to severe permanent swelling of the affected part of the body. It is more often found in the upper extremities of women with breast cancer. It may, however, appear at one or more extremities and may include the corresponding quadrant of the trunk. It may also affect head and neck, breast, genitals and lower extremities, depending on the surgery the patient has undergone. It is often associated with obesity (BMI>40). Early diagnosis and treatment of lymphedema is related with better therapeutic outcome. Women with breast cancer confront more problems with lymphedema than with mastectomy. Its effect on patients' quality of life is relevant to changes in body image, self-esteem, feelings of weakness, fear and anxiety about disease progression, financial costs, and reduced limb function. More recent studies support the effectiveness of contemporary surgical techniques in lymphedema's treatment. In conservative management, CDT remains the treatment of choice and in combination with exercise, weight control programs and self-care training seems to significantly improve patients' quality of life.Molecular biology of cancer cell is a domain of medical science that is rapidly growing in our days. Knowing the ways and paths that cancer cells follow is crucial to the prevention of cancer itself. Central role to these paths, concerning the cell cycle and the process of apoptosis, has the protein p53. The whole mechanism of the cell cycle is activated by the action of various mitogens, such as growth factors, hormones and cytokines. Carcinogenesis involves alterations of genes (proto-oncogenes and tumor suppressor genes), which encode proteins of the signal transduction. Many of the damages that lead to carcinogenesis may be due to the lack of repressive signals for cell division, but also to the absence of the sensitivity of cells to repressive signals. The cell has mechanisms of receiving apoptotic-antitumor signals and mechanisms of execution of these instructions. A percentage of cancers (4-8%) are etiologically linked to germ (stem) cells mutations and occur at an increased frequency in families (hereditary cancers). Substantial progress in understanding the mechanisms of carcinogenesis, filtration and metastasis of cancer has highlighted the key role of specific genes, primarily oncogenes and tumor suppressor genes.Coronavirus-related Severe Acute Respiratory Syndrome (SARS-CoV) in 2002/2003, Middle-East Respiratory Syndrome (MERS-Cov) in 2012/2013, and especially the current 2019/2020 Severe Acute Respiratory Syndrome-2 (SARS-CoV-2) tested the national health systems' endurance worldwide. In order to fight this emergency situation, a variety of pharmaceutical companies focused on the design and development of efficient vaccines that are considered necessary for providing a level of normalization in totally affected human social-economical activity worldwide. COVID-19 led to an increased uncertainty in the field of oncological patients' management disrupting the normal conditions of therapeutic and monitoring procedures. In the current article, we explored the impact of SARS-CoV-2 infection on oral carcinoma patients. We observed COVD-19 pandemic negatively affects the normality regarding early diagnosis and optimal management (surgical operation, post-operational follow up/monitoring) in HNSCC/OSCC patients. Understanding the involvement of SARS-CoV-2 in the progression of malignancies is the first critical step for targeting the virus by efficient monoclonal antibodies and vaccines.Despite its well known harmful effects on health, tobacco use is widespread throughout the world. Approximately one third of the global population become smokers at the age of 15 years or more. The prevalence of smoking between genders is lessening. Earlier, men used to smoke three to four times more than women globally. The nicotine content of cigarette is small (10 to 12 mg) and a smoker inhales about 1.1 to 1.8 mg of nicotine from each cigarette smoked to its entire length; this plant alkaloid stimulates the central nervous system, causes either ganglionic stimulation in low doses or ganglionic blockade in high doses, and smokers can develop a moderate to heavy physical dependence. Among other numerous substances, several are cancerogenic, and about 98 percent of lung cancer deaths are caused due to tobacco smoke. Nicotine addiction is often more severe than alcohol addiction. Smoking also may complicate anesthetic management, and passive smoking increases the rate of perioperative airway complications in the children of smokers, too.
