Triple-negative breast cancer (TNBC) is the most aggressive and fatal subtype of breast cancer. The effectiveness of platinum-based neoadjuvant chemotherapy in treatment of cancer has many divergent opinions. A search was conducted in the PubMed, EBSCO, Web of Science and Cochrane Library databases for relevant studies published before August 2020. The primary endpoint was pathological complete response (pCR) while the secondary endpoints were objective response rate (ORR), overall survival (OS) and progression-free survival (PFS). Nine randomized controlled trials comprised of 1873 patients were included in this meta-analysis. Platinum-based neoadjuvant chemotherapy showed significant improvements in pCR (RR = 1.51, 95% CI, 1.25-1.82, P < 0.001), ORR (RR = 1.20, 95% CI, 1.07-1.34, P = 0.001), OS (HR=0.56; 95% CI, 0.15-0.96, P < 0.001) and PFS (HR = 0.48, 95% CI, 0.22-0.73, P < 0.001) compared to nonplatinum neoadjuvant chemotherapy. Moreover, addition of platinum compounds did not significantly increase the side effects of any grade. However, there was an increase in blood toxicity of grade 3 patients which meant that it was mainly confined to the bone marrow/blood system. Platinum-based neoadjuvant chemotherapy can safely improve short-term and long-term outcomes in resectable TNBC patients.

Therapeutic hurdles persist in the fight against lung cancer, although it is a leading cause of cancer-related deaths worldwide. Results are still not up to par, even with the best efforts of conventional medicine, thus new avenues of investigation are required. Examining how immunotherapy, precision medicine, and AI are being used to manage lung cancer, this review shows how these tools can change the game for patients and increase their chances of survival.

Introduction: Soft-tissue sarcomas arising in the thigh may require total or subtotal compartmentectomy, with subsequent need for functional reconstruction with free functional muscle transfer (FFMT). We present our series, describing a new approach with chimeric propeller antero-lateral thigh-vastus lateralis (ALT-VL) free flap, which allows for independent muscle inset and soft tissue defect resurfacing.
Patient And Methods: A retrospective review of a prospectively maintained database was performed, analyzing all patients referred to Fondazione Policlinico Universitario Campus Bio-Medico, Rome, Italy, between 2018 and 2023 for soft-tissue sarcomas of the thigh requiring wide excision and reconstruction with functional ALT-VL.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a major side effect associated with chemotherapy. It can lead to detrimental dose reductions and discontinuation of treatment because of its significant effect, which impairs the quality of life among the surviving population of cancer patients. This study assesses the prevalence and predictors of CIPN among female breast cancer patients receiving chemotherapy at the Lagos University Teaching Hospital and Lagos State University Teaching Hospital (LUTH and LASUTH), respectively.

Background: There is limited data from India on Ewing sarcoma (ES) patients. We analysed the demographic and clinical profile of ES patients, the systemic chemotherapy, local treatment and outcomes in patients with localised, metastatic and recurrent disease.
Methods: Data of ES patients reporting from 2010 to 2019 to a tertiary care referral centre in north India was evaluated.

Background: In recent years, the incidence of pancreatic cancer has shown an obvious increasing trend worldwide and even causes a greater disease burden to the mankind. Due to the lack of effective early surveillance methods, patients are often in the middle to advanced stages of their disease at the time of detection, thus losing the opportunity for surgery. The currently available chemotherapy regimens are yet to be further improved to prolong patient survival.
