AI Article Synopsis
- Cisplatin-based chemotherapy was given to patients across various treatment lines, showing a 53.9% response rate in first-line treatment compared to 30.6% in later lines.
- Statistical analysis indicated significantly better overall and disease-free survival for those receiving first-line chemotherapy, especially among women (p = 0.05).
- Toxicities were generally mild to moderate, with more severe effects noted in later-line treatments; notably, "bolus" CDDP showed better outcomes compared to CVI CDDP.
Article Abstract
Cisplatin containing regimens as first-line, second-line or as a third-line chemotherapy were administered in 26 and 36 patients, respectively. The overall response rate in patients on first-line chemotherapy was 53.9%, in patients on second or third-line chemotherapy 30.6%. The differences both in overall and disease-free survival between patients on first-line and on second/third-line chemotherapy were statistically significant in favor of women treated with first-line chemotherapy (p = 0.05). Hematologic and nonhematologic toxicities were mild to moderate and were more pronounced in patients on second and third-line chemotherapy. The overall response rate, DFS and OS were significantly better and longer in the group of patients treated with "bolus" CDDP in comparison to the group of patients treated with CVI CDDP. Our results confirm the activity of cisplatin-containing regimens (mainly CAP schedules) in patients with advanced breast cancer not only as a first-line therapy but also in heavily pretreated patients by chemotherapy and/or radiation therapy and endocrine manipulation.

Efficacy and safety of anlotinib as maintenance treatment in extensive-stage small cell lung cancer: a single-armed single center retrospective study.
Front Oncol
January 2025
Department of Cancer Center, The Second Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Introduction: Patients with extensive-stage small cell lung cancer (ES-SCLC) have a poor Q6 prognosis and there is no standard protocol for maintenance treatment. Anlotinib as a third-line or beyond therapy for ES-SCLC was proved to be effective.
Methods: We retrospectively screened of patients with ES-SCLC who started receiving anlotinib as first-line or second-line therapy at the Second Affiliated Hospital of Chongqing Medical University from November 2018 to December 2022.
Tenofovir and Doravirine Are Potential Reverse-Transcriptase Analogs in Combination with the New Reverse-Transcriptase Translocation Inhibitor (Islatravir) Among Treatment-Experienced Patients in Cameroon: Designing Future Treatment Strategies for Low- and Middle-Income Countries.

Islatravir (ISL) is a novel antiretroviral that inhibits HIV-1 reverse transcriptase translocation. The M184V mutation, known to reduce ISL's viral susceptibility in vitro, could arise from prolonged exposure to nucleoside reverse transcriptase inhibitors (NRTI) (3TC). This study evaluated the predictive efficacy of ISL and identified potentially active antiretrovirals in combination among treatment-experienced patients in Cameroon, where NRTIs (3TC) have been the backbone of ART for decades now.

Background: Both aflibercept and bevacizumab-based regimens are available II-line treatment options for patients with metastatic colorectal cancer (mCRC). However, no head-to-head trials established the optimal anti-angiogenic strategy for this setting.
Methods: We launched a multicenter, retrospective, observational study to assess and compare clinical efficacy of II-line treatments for patients with mCRC.

Comparative effectiveness of antipsychotic treatment strategies for relapse prevention in first-episode schizophrenia in Finland: a population-based cohort study.

Background: The best pharmacological treatment practices for relapse prevention in patients with first-episode schizophrenia are unclear. We aimed to assess different treatment strategies used before and after the first relapse, and their associations with subsequent relapse risk.
Methods: In this population-based cohort study, we enrolled individuals (aged ≤45 years) with first-episode schizophrenia who were hospitalised and subsequently relapsed between 1996 and 2014 from the nationwide Finnish Hospital Discharge Register.
