Objective To investigate the impact of cumulative cisplatin dose on clinical outcomes in locally advanced cervical cancer patients undergoing definitive chemoradiotherapy. Methods A retrospective analysis was conducted on 654 patients with stage IB3–IVA disease treated with definitive chemoradiotherapy. Radiotherapy was applied as external beam pelvic with or without para-aortic radiotherapy and brachytherapy. Concomitant chemotherapy was in the form of weekly or 3 weekly cisplatin. Data on demographics, treatment protocols, cumulative cisplatin dose, adverse effects, and survival outcomes were collected. Statistical analyses, including univariate and multivariate Cox regression models, were used to assess factors influencing progression free survival and overall survival. Results The median cumulative cisplatin dose was 210 mg (range 40–320), and ≥200 mg in 503 (76.9%) patients. Median follow-up was 35 months (range 1–150). The 5 year progression free survival and overall survival rates were 66.9% and 77.1%, respectively. Multivariate analysis identified poor performance status, non-squamous cell histology, presence of lymph node metastases, and hemoglobin <10 g/dL before chemoradiotherapy as poor prognostic factors for both progression free survival and overall survival in the whole group. When stage III cases were evaluated separately, the cumulative cisplatin dose 200 mg, particularly in patients with lymph node metastases, significantly improved overall survival. Factors such as anemia, toxicity related challenges, and comorbidities were identified as critical considerations in treatment planning. These findings emphasize the balance between maximizing therapeutic efficacy and managing toxicity, guiding personalized treatment approaches for locally advanced cervical cancer.

Although microtubule inhibitors are generally used in advanced stages, they provide the opportunity to prolong survival as an alternative when medical oncologists have difficulty finding options in their patients, who typically have a poor prognosis and most of whom are unresponsive to treatment. For this reason, we wanted to investigate the effect of ixabepilone treatment on survival in earlier metastatic lines. Our study also examined the frequency of side effects and survival differences in patients whose dose was reduced or whose treatment was discontinued. Our study includes patients diagnosed with metastatic breast cancer who received ixabepilone treatment between January 2011 and January 2021. Median overall survival (OS) in the group receiving ixabepilone on the 5th line and before was 22.0 months (95% CI: 21.0–22.9), in the group receiving ixabepilone after the 5th line was calculated as 10.0 months (95% CI: 8.9–11.0) (P < .001). Median OS (months) in the group receiving ixabepilone on the 4th line and before was 26.0 (95% CI: 23.6–28.3), in the group receiving ixabepilone after the 4th line was determined as 12.0 (95% CI: 10.5–13.4) (P < .001). Dose reduction or discontinuation of ixabepilone treatment in patients due to side effects did not affect OS and progression-free survival with ixabepilone statistically significantly. Ixabepilone treatment has side effects, similar to all other treatments used in metastatic breast cancer, however, these side effects are manageable. Additionally, since ixabepilone treatment is preferred in patients who have previously received many different chemotherapeutics and experienced cumulative toxicity, the side effects of ixabepilone may seem to be greater than they are. In our study, we showed that ixabepilone treatment has a statistically significant positive effect on survival if preferred in earlier metastatic lines. As similar studies increase in centers where ixabepilone treatment is generally given in advanced metastatic lines, treatment approaches may change in the coming years.

Background: Hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer frequently involves liver metastases, which are linked to poor outcomes. The optimal first-line treatment strategy in this subgroup remains unclear. Methods: This multicenter, retrospective study evaluated 121 patients with HR-positive, HER2-negative breast cancer and liver metastasis who had not received prior systemic chemotherapy or cyclin-dependent kinase (CDK) 4/6 inhibitors (e.g., palbociclib, ribociclib). Patients were classified based on their initial treatment during the liver metastatic phase (CDK4/6 inhibitors or chemotherapy). Clinical characteristics, treatment patterns, and survival outcomes were assessed. Cox regression analysis identified independent prognostic factors. Results: The median age was 53 years; 62% were postmenopausal. Chemotherapy was administered to 36.4%, and CDK4/6 inhibitors to 63.6% of patients. Most cases (59.5%) were recurrent disease. Baseline characteristics were comparable, except for the use of local liver-directed therapies. Progression-free survival favored CDK4/6 inhibitors (10.9 vs. 4.8 months; p < 0.01), while overall survival favored chemotherapy (42.2 vs. 25.9 months; p = 0.042). In multivariate analysis, initial treatment modality, local liver-directed therapy, hormonal status, and the size of the largest liver lesion were independent predictors of survival. Conclusions: In patients with HR-positive, HER2-negative breast cancer and liver metastasis, first-line chemotherapy was associated with improved overall survival compared to CDK4/6 inhibitors. Local liver-directed therapies contributed to longer survival, while larger liver lesions and endocrine-resistant disease correlated with worse outcomes. These findings support considering chemotherapy as first-line treatment in selected patients with aggressive liver metastatic disease.

Kaposi sarcoma (KS) is a rare disease caused by human herpesvirus-8 (HHV-8) infection, that occurs in the elderly and more often in men. We aimed to compare the clinical and prognostic features of patients with classic and AIDS-related KS who have been followed in our clinic over the last 10 years and to present real-life data in first-line treatment. We retrospectively reviewed the medical records of 73 patients with KS, 57 with classic KS and 16 with acquired immunodeficiency syndrome (AIDS)-related KS, who were followed up at our clinic between January 2014 and December 2023. Information analyzed included demographic characteristics, clinical features, treatment modalities and prognosis of the patients. The median follow-up period was 44 months in the classic KS group and 20 months in the AIDS-related group. The median age at diagnosis of classic KS patients was 67 years and 82.5% of the patients were male. The median age at diagnosis of AIDS-related KS patients was 41 years and all patients were male. The majority of patients had an Eastern Cooperative Oncology Group performance status of 0 or 1, and comorbidities were more common in the classic KS group. The most common site of involvement in both groups was the lower extremity. 48% and 69% of patients with classic KS and AIDS-related KS, respectively, received first-line systemic chemotherapy. All patients with AIDS-related KS received antiretroviral therapy. Paclitaxel was the most preferred first-line agent in both groups. An optimal overall response rate of 78% was achieved in patients with both classic KS and AIDS-related KS. 5-year overall survival was 75% in patients with classic KS and 93% in patients with AIDS-related KS. This real-world, single-center experience provides insight into the management of patients with KS in a developing country and highlights the need to improve access to standard first-line treatment.

Background: The aim of this study is to investigate whether vitamin D, calcium, ferritin, and uric acids play a beneficial biomarker role in the prevention of colorectal cancer (CRC) risk. Methods: The case-control design was employed, including 650 CRC cases and 650 controls aged 35 to 70 years, comprising both men and women. The study encompasses sociodemographic data, clinical information, radiological diagnoses, and biochemical measurements. Results: Statistically significant differences were observed between CRC and controls in terms of age, diagnostic radiology, tomography, positron emission tomography/computed tomography (PET/CT), colonoscopy, CRC awareness, risk factors, age, genetics, exposure to chemicals, inadequate nutrition, smoking, hookah and alcohol use. Significant differences were also identified in intestinal inflammations, obesity, processed foods (P < 0.001), abdominal pain and cramps, diarrhea, constipation, blood in stool, bloating (gas), irritable bowel, nausea/vomiting, anemia, stress, fatigue, weakness, and weight loss. Regarding biochemical parameters, statistically significant differences were found between CRC and controls in terms of hemoglobin, glycated hemoglobin (HbA1c), fasting blood glucose (FBG), vitamin D, neutrophil level, red blood cell (RBC), white blood cell (WBC), platelet level, platelet count, hematocrit, potassium, sodium (Na), calcium, creatinine, cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), bilirubin, uric acid, iron (Fe), ferritin, C-reactive protein (CRP), total protein, systolic blood pressure (SBP), and diastolic blood pressure (DBP) parameters (P < 0.001). Multivariate stepwise regression analysis was performed to find the best risk factors for the diagnosis of CRC as the dependent variable. As a result of the analysis, intestinal inflammation (P < 0.001), nausea/vomiting (P < 0.001), stomach pain (P = 0.003), hookah-smoking (P = 0.034), uric acid (P < 0.001), bilirubin (P < 0.001), cigarette smoke exposure (P = 0.033), processed food consumption (P = 0.002), calcium levels (P = 0.029), vitamin D deficiency (P < 0.001), and ferritin (P < 0.001) levels were identified as significant determinants for CRC. Conclusions: The current study demonstrated that vitamin D, calcium, ferritin, and uric acids play a beneficial biomarker role in reducing the risk of CRC prevention. The increase in CRC rates may be associated with lifestyle, environmental and hereditary factors, nutrition, alcohol consumption, hookah use, and cigarette smoking.
