Background: There have been few reports on cancer patients with COVID-19 since its outbreak. Our study aimed to understand the clinical features of cancer patients with COVID-19 and determine the impact of surgery and chemotherapy on the patients' conditions.
Methods: Seventy COVID-19 patients from Renmin Hospital of Wuhan University, including 18 cancer patients, were enrolled in this study. Patients were classified into moderate or severe cases of COVID-19 and as well as non-cancer or cancer patients. Cancer patients were further grouped into Group A (prevalent cases with cancer history) and Group B (incident cases who underwent cancer treatment recently). Laboratory results were analyzed to determine whether cancer-related surgery and chemotherapy worsened the condition of cancer patients. The patients presented with clinical symptoms of COVID-19, including fever, dry cough, and polypnea; blood tests also revealed decreased lymphocyte counts and cellular immune function, and examination of CT scans revealed patchy ground-glass opacity of lungs.
Results: The results showed a significant difference (P<0.05) in levels of CD3 CD4 T lymphocytes and D-dimer between non-cancer and cancer patients with moderate COVID-19; there was also a significant difference (P<0.05) in levels of D-dimer between non-cancer and cancer patients with severe COVID-19. Except for liver function, there was no significant difference (P>0.05) between cancer patients in Group A and B with moderate COVID-19. A significant difference (P<0.05) in neutrophil-to-lymphocyte ratio (NLR) and CD4 T lymphocytes was observed between cancer patients with moderate COVID-19 and those with severe COVID-19.
Conclusions: The results indicated that chemotherapy and surgery might not worsen the conditions of COVID-19 patients. NLR and CD4 T lymphocyte might be used as effective indicators for the conditions of cancer patients with COVID-19.

Background: The availability and affordability of safe, effective cancer therapies are core requirements for effective cancer control. Global disparities exist in access, however, yielding unequal cancer outcomes. The goal of this study was to provide updated data regarding the formulary availability, out-of-pocket costs, and accessibility of cancer medicines in countries across the full spectrum of economic development areas.

Background: In pancreatic surgery Postoperative pancreatic fistula (POPF) represents the most dreaded complication, for which pancreatic texture is acknowledged as one of the strongest predictors. No consensual objective reference has been defined to evaluate the pancreas composition. The presented study aimed to mine histology data of the pancreatic tissue composition with AI assist and correlate it with clinic-pathological parameters derived from the RECOPANC study.

Background: To evaluate the real-world surgical and pathological outcomes following neoadjuvant nivolumab in combination with chemotherapy in a multicentre national cohort of patients.
Methods: Retrospective analysis on consecutive patients treated in three tertiary referral hospitals in UK with neoadjuvant chemotherapy and immunotherapy (nivolumab) for stage II-IIIB nonsmall cell lung cancer (March 2023-May 2024). Surgical and pathological outcomes were assessed.

Objective: To determine the association between concurrent statin use with immune checkpoint inhibitors (ICIs) and lung cancer-specific and overall mortality in patients with nonsmall cell lung cancer (NSCLC).
Materials And Methods: SEER-Medicare was used to conduct a retrospective study of Medicare beneficiaries ≥65 years of age diagnosed with NSCLC between 2007 and 2017 treated with an ICI. Patients were followed from date of first ICI claim until death, 1 month from last ICI claim, or 12/31/2018, whichever came first.

Uganda's only radiotherapy center is a very busy facility treating about 210 patients daily on three linear accelerators making it sometimes hard to have machine time for pretreatment QAs. This study was aimed at validating an independent calculation software, ClearCalc (ICS) for second checks of the treatment planning system (TPS) calculations. The validation of ICS started with simple phantom test plans consisting of square, irregular, open and wedged fields designed in the TPS and measured in phantoms.
