PURPOSE: MRI-only adaptive brachytherapy (MRI-ABT) is the state-of-the-art for treating locally advanced cervical cancer (LACC) in combination with concurrent chemoradiotherapy. We aimed to evaluate the pattern of pelvic recurrence after the treatment. MATERIAL AND METHODS: A total of one hundred LACC patients were treated between January 2017 and December 2023 with concurrent chemoradiotherapy of 45 Gy in 25 fractions ± boost to lymphadenopathy (up to a maximum dose of 60 Gy in 25 fractions) with concurrent weekly cisplatin chemotherapy at the dose of 40 mg/m2/week, and MR-ABT. RESULTS: At a median follow-up of 30.2 months, there were 2 local recurrences (2%) and 9 regional pelvic recurrences (9%). The median time to local/regional recurrence was 11 months (range 6-21). For all stages, the 3-year local control was 97.66%, and the 3-year pelvic control was 89.45%. Twenty-four patients died during follow-up; the 3-year overall survival was 75.11%, and the 3-year disease-free survival was 70.97%. CONCLUSION: MRI-ABT combined with external beam radiotherapy and concurrent chemotherapy for LACC demonstrates excellent local and regional pelvic control. Most local/regional recurrences occur inside or at the edge of the external-beam irradiated field. Recurrences inside the field of brachytherapy are rare. Distant recurrences are the predominant cause of death in LACC patients treated with definitive CRT and MRI-ABT.

Platinum(IV) compounds possess distinct properties that set them apart from platinum(II) compounds. Often designed as prodrugs, they are reduced within cancer cells to their active platinum(II) form, enabling their cytotoxic effects. Their versatility also lies in their ability to be functionalized and conjugated with bioactive molecules to enhance cancer cell targeting. This report introduces new prodrugs that combine antitumor cisplatin with axially coordinated eugenol, leveraging their synergistic action to target cancer stem cells. A third bioactive ligand, 4-phenylbutyrate or octanoate, was added to further enhance biological activity, creating 'triple action' prodrugs. These new platinum(IV) prodrugs offer a novel approach to cancer therapy by improving targeting, increasing efficacy, overcoming drug resistance, and reducing tumor invasiveness while sparing healthy tissue.

Breast cancer is a prevalent and aggressive disease characterized by high metastasis, recurrence, and mortality rates. While cisplatin is an effective chemotherapy drug, its use is limited by its toxic effects on the body. Despite advancements in therapeutic strategies, the therapeutic response is often unsatisfactory due to drug resistance, leading to poor prognosis. Recent studies have shown that cisplatin interacts with long non-coding RNAs (lncRNAs) and accelerates the development of resistance in tumor cells to therapy. This interaction highlights the complex mechanisms involved in the response of cancer cells to chemotherapy. Several lncRNAs have been identified as key players in mediating cisplatin resistance in breast cancer. These lncRNAs include SNHG15, HULC, HCP5, MT1JP, LncMat2B, DLX6-ASL, Linc00665, CARMN, and Lnc-EinRP44-3:6. These lncRNAs have been shown to target microRNAs and mRNAs and modulate the expression of genes involved in cisplatin resistance, which is important in treating breast cancer.

BACKGROUND: Neoadjuvant chemotherapy followed by radical cystectomy is the standard treatment for cisplatin-eligible patients with muscle-invasive bladder cancer. Adding perioperative immunotherapy may improve outcomes. METHODS: In this phase 3, open-label, randomized trial, we assigned, in a 1:1 ratio, cisplatin-eligible patients with muscle-invasive bladder cancer to receive neoadjuvant durvalumab plus gemcitabine-cisplatin every 3 weeks for four cycles, followed by radical cystectomy and adjuvant durvalumab every 4 weeks for eight cycles (durvalumab group), or to receive neoadjuvant gemcitabine-cisplatin followed by radical cystectomy alone (comparison group). Event-free survival was one of two primary end points. Overall survival was the key secondary end point. RESULTS: In total, 533 patients were assigned to the durvalumab group and 530 to the comparison group. The estimated event-free survival at 24 months was 67.8% (95% confidence interval [CI], 63.6 to 71.7) in the durvalumab group and 59.8% (95% CI, 55.4 to 64.0) in the comparison group (hazard ratio for progression, recurrence, not undergoing radical cystectomy, or death from any cause, 0.68; 95% CI, 0.56 to 0.82; P<0.001 by stratified log-rank test). The estimated overall survival at 24 months was 82.2% (95% CI, 78.7 to 85.2) in the durvalumab group and 75.2% (95% CI, 71.3 to 78.8) in the comparison group (hazard ratio for death, 0.75; 95% CI, 0.59 to 0.93; P = 0.01 by stratified log-rank test). Treatment-related adverse events of grade 3 or 4 in severity occurred in 40.6% of the patients in the durvalumab group and in 40.9% of those in the comparison group; treatment-related adverse events leading to death occurred in 0.6% in each group. Radical cystectomy was performed in 88.0% of the patients in the durvalumab group and in 83.2% of those in the comparison group. CONCLUSIONS: Perioperative durvalumab plus neoadjuvant chemotherapy led to significant improvements in event-free survival and overall survival as compared with neoadjuvant chemotherapy alone.

Cisplatin is a widely used chemotherapy drug for the treatment of various cancers. However, although cisplatin is effective in targeting cancer cells, it has severe side effects including skeletal muscle atrophy. In this study, we aimed to characterize the role of Dihydromyricetin in cisplatin-induced muscle atrophy in mice. 5-week-old male C57BL/6 mice were treated with Dihydromyricetin for 14 days orally followed by in intraperitoneally cisplatin administration for 6 days. Gastrocnemius muscles were isolated for the following experiments. Antioxidative stress were determined by peroxidative product malondialdehyde (MDA) and antioxidants superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities. Quadriceps muscle mass and grip strength were significantly restored by Dihydromyricetin in a dose-dependent manner. Moreover, muscle fibers were improved in Dihydromyricetin treated group. Excessive skeletal muscle E3 ubiquitin-protein ligases in cisplatin group were significantly repressed by Dihydromyricetin treatment. Dihydromyricetin significantly reduced oxidative stress induced by cisplatin by decreasing MDA level and restored SOD and GPx activities. In addition, ferroptosis was significantly reduced by Dihydromyricetin characterized by reduced iron level and ferritin heavy chain 1 and improved Gpx4 level. The present study demonstrated that Dihydromyricetin attenuated cisplatin-induced muscle atrophy by reducing skeletal muscle E3 ubiquitin-protein ligases, oxidative stress, and ferroptosis.

PURPOSE: Chemotherapy can potentially enhance the activity of immune checkpoint inhibitors by promoting immune priming. The phase Ib/II JAVELIN Chemotherapy Medley trial (NCT03317496) evaluated first-line avelumab + concurrent chemotherapy in patients with advanced urothelial carcinoma or non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Avelumab 800 or 1,200 mg was administered continuously every 3 weeks with standard doses of cisplatin + gemcitabine in patients with urothelial carcinoma, or carboplatin + pemetrexed in patients with nonsquamous NSCLC. Dual primary endpoints were dose-limiting toxicity (DLT; phase Ib) and confirmed objective response (phase Ib/II). RESULTS: In phase Ib, urothelial carcinoma and NSCLC cohorts received avelumab 800 mg (n = 13 and n = 6, respectively) or 1,200 mg (n = 6 each) + chemotherapy. In evaluable patients with urothelial carcinoma treated with avelumab 800 or 1,200 mg + chemotherapy, DLT occurred in 1/12 (8.3%) and 1/6 (16.7%), respectively; no DLT occurred in the NSCLC cohort. In phase II, 35 additional patients with urothelial carcinoma received avelumab 1,200 mg + chemotherapy. Across all treated patients, safety profiles were similar irrespective of avelumab dose. Objective response rates (95% confidence internal) with avelumab 800 or 1,200 mg + chemotherapy, respectively, across phase Ib/II, were 53.8% (25.1-80.8) and 39.0% (24.2-55.5) in urothelial carcinoma, and 50.0% (11.8-88.2) and 33.3% (4.3-77.7) in NSCLC. CONCLUSIONS: Preliminary efficacy and safety findings with avelumab + chemotherapy in urothelial carcinoma and NSCLC were consistent with previous studies of similar combination regimens. Conclusions about clinical activity are limited by small patient numbers. SIGNIFICANCE: This phase Ib/II trial evaluated avelumab (immune checkpoint inhibitor) administered concurrently with standard first-line chemotherapy in patients with advanced urothelial carcinoma or advanced nonsquamous NSCLC without actionable mutations. Efficacy and safety appeared consistent with previous studies of similar combinations, although patient numbers were small.

Herein, we describe the general design, synthesis, characterization, and biological activity of new multitargeting Pt(IV) prodrugs that combine antitumor cisplatin and dasatinib, a potent inhibitor of Src kinase. These prodrugs exhibit impressive antiproliferative and anti-invasive activities in tumor cell lines in both two-dimensional (2D) monolayers of cell cultures and three-dimensional (3D) spheroids. We show that the cisplatin moiety and dasatinib in the investigated Pt(IV) complexes are both involved in the mechanism of action in MCF7 breast cancer cells and act synergistically. Thus, combining dasatinib and cisplatin into one molecule, compared to using individual components in a mix, may bring several advantages, such as significantly higher activity in cancer cell lines and higher selectivity for tumor cells. Most importantly, Pt(IV)-dasatinib complexes hold significant promise for potential anticancer therapies by targeting epithelial-mesenchymal transition, thus preventing the spread and metastasis of tumors, a value unachievable by a simple combination of both individual components.

Nephrotoxicity as a cause of acute kidney injury (AKI) induced by cisplatin (CP), limits its usefulness as an anticancer agent. Diminazene, an angiotensin converting enzyme 2 activator, exhibited renoprotective properties on rat models of kidney diseases. This research aims to investigate the salutary effect of diminazene in comparison with lisinopril or valsartan in CP-induced AKI. The first and second groups of rats received oral vehicle (distilled water) for 9 days, and saline injection or intraperitoneal CP (6 mg/kg) on day 6, respectively. Third, fourth, and fifth groups received intraperitoneal injections of CP on day 6 and diminazene (15 mg/kg/day, orally), lisinopril (10 mg/kg/day, orally), or valsartan (30 mg/kg/day, orally), for 9 days, respectively. 24h after the last day of treatment, blood and kidneys were removed under anesthesia for biochemical and histopathological examination. Urine during the last 24 h before sacrificing the rats was also collected. CP significantly increased plasma urea, creatinine, neutrophil gelatinase-associated lipocalin, calcium, phosphorus, and uric acid. It also increased urinary albumin/creatinine ratio, N-Acetyl-beta-D-Glucosaminidase/creatinine ratio, and reduced creatinine clearance, as well the plasma concentrations of inflammatory cytokines [plasma tumor necrosis factor-alpha, and interleukin-1beta], and significantly reduced antioxidant indices [catalase, glutathione reductase , and superoxide dismutase]. Histopathologically, CP treatment caused necrosis of renal tubules, tubular casts, shrunken glomeruli, and increased renal fibrosis. Diminazine, lisinopril, and valsartan ameliorated CP-induced biochemical and histopathological changes to a similar extent. The salutary effect of the three drugs used is, at least partially, due to their anti-inflammatory and antioxidant effects. Keywords: Cisplatin, Diminazene, ACE2 activator, Lisinopril, Valsartan, Acute kidney injury.

Extenzivní stadium malobuněčného plicního karcinomu (extensive-stage small cell lung cancer, ES-SCLC) je malignita se stále špatnou prognózou. Pacienti s ES-SCLC by měli být v první linii první čtyři cykly léčeni kombinací platiny s etoposidem a s durvalumabem anebo s atezolizumabem, následně by měli pokračovat udržovací imunoterapií. Zmíněná kombinační léčba zlepšuje přežití nemocných. Tato kazuistika popisuje případ 68leté pacientky, která je durvalumabem úspěšně léčena.

Extensive-stage small cell lung cancer (ES-SCLC) is a malignancy with a still poor prognosis. Patients with ES-SCLC should be treated with first-line platinum and etoposide plus either durvalumab or atezolizumab for four cycles followed by maintenance immunotherapy. Mentioned combination therapy improves survival of patients. This clinical case reports a successful treatment with durvalumab of a 68 years old patient.
