OBJECTIVE: There is no agreed-upon standard option for patients with locally advanced head and neck squamous cell carcinoma (LA HNSCC) unfit for cisplatin-based regimens. Therefore, we performed a systematic review to explore alternative options for this population.
METHODS: We searched PubMed, Cochrane, and Embase databases for observational studies and clinical trials (CTs) assessing treatment options for LA HNSCC cisplatin-ineligible patients. This study was registered in PROSPERO under the number CRD42023483156.
RESULTS: This systematic review included 24 studies (18 observational studies and 6 CTs), comprising 4450 LA HNSCC cisplatin-ineligible patients. Most patients were treated with cetuximab-radiotherapy [RT] (50.3%), followed by carboplatin-RT (31.7%). In seven studies reporting median overall survival (OS) in patients treated with cetuximab-RT, it ranged from 12.8 to 46 months. The median OS was superior to 40 months in two studies assessing carboplatin-RT, and superior to 15 months in two studies assessing RT alone. For other regimens such as nimotuzumab-RT, docetaxel-RT, and carboplatin-RT plus paclitaxel the median OS was 21, 25.5, and 28 months, respectively.
CONCLUSIONS: Our systematic review supports the use of a variety of therapy combinations for LA HNSCC cisplatin-ineligible patients. We highlight the urgent need for clinical studies assessing treatment approaches in this population.

UNASSIGNED: Endometrial carcinoma is the most widespread gynecological cancer, with increasing morbidity and mortality. Pembrolizumab, a monoclonal antibody that targets PD1 receptor tumors, is approved for patients with microsatellite instability-high (MSI-H) solid tumors. Many clinical trials and observational studies have been conducted to assess the safety and efficacy of Lenvatinib and Pembrolizumab combination therapy in the setting of endometrial cancer. However, results have been inconsistent, and current data is based on a heterogeneous population. The primary objective was to assess the safety and efficacy of Lenvatinib plus Pembrolizumab for endometrial cancer.
UNASSIGNED: The search was conducted from inception from four databases; PubMed, Google Scholar, the Cochrane Library, and ClinicalTrials.gov. The electronic database search was conducted from inception to August 20, 2023.
UNASSIGNED: We considered randomized controlled trials and single-arm observational studies, i.e. cohort, case-control and cross-sectional studies.
UNASSIGNED: We performed a single-arm meta-analysis, involving 7 studies having a total of 495 patients with endometrial cancer were eventually included which had the following outcomes: Complete response, Partial response, Progression-free survival, stable disease, progressive disease, safety outcomes, Adverse events, and the total number of deaths.
UNASSIGNED: Our results showed that 88.6 % of the patients were positive for non-MSI-H/pMMR tumors (95 % CI = 0.825-0.927) whereas 6.5 % (95 % CI = 3.8-9.8 %) of the patients for MSI-H/dMMR tumors. The pooled objective response of endometrial cancer patients treated with Lenvatinib and Pembrolizumab was 36.5 % (95 % CI = 0.258-0.471), the pooled estimate of complete and partial response was 47 % (95 % CI = 0.024-0.070) and 31.3 % (95 % CI = 0.230-0.396). 38.2 % patients had stable disease (95 % CI = 0.329-0.435) and 24.0 % patients had progressive disease (95 % CI = 0.103-0.378). The pooled median progression-free survival was 5.97 (95 % CI 5.43-7.63) months and, whereas the median overall survival was 17.19 months (95 % CI 15.34-19.31). All grade adverse events occurred in 85 % and Grade 3 or worse adverse events occurred in 39 % of patients during the therapy whereas death occurred in 23.8 % during the treatment.
UNASSIGNED: The results of this meta-analysis concludes that although the combined treatment of a Lenvatinib and Pembrolizumab had a PFS and OS that was inferior to the standard therapy used to treat advanced and recurrent endometrial cancer, it is still a novel treatment and shows potential for further research with a greater sample size.

Introduction: The combination therapy of platinum and pembrolizumab looks like a promising treatment in advanced non-small-cell lung cancer. However, both platinum-based chemotherapy and pembrolizumab can lead to AKI. AKI can occur due to acute tubular necrosis or interstitial nephritis. It is essential to identify the drug responsible for renal damage. For this purpose, we used new immunohistochemistry markers (p53 and anti-PD1 analysis). Case Description: A 77-year-old female patient with advanced non-small-cell lung cancer received the PD-1 inhibitor pembrolizumab and platinum-based chemotherapy carboplatin. The patient, after 60 days, experienced AKI. A kidney biopsy was performed, and two new immunohistochemical techniques for p53 (experimental markers of ATN from platinum) and anti-PDL1 (experimental markers of PD-1 inhibitors nephritis) were employed. Renal biopsies revealed severe tubular damage. No infiltration was detected, and the immunohistochemical assessment of PDL-1 was negative. The expression of p53 was positive. The renal biopsy suggested platinum-induced acute tubular necrosis. After discontinuing steroids and reducing carboplatin, the patient continued with pembrolizumab, and their renal function returned to normal within two months. Discussion: Combining checkpoint inhibitors and platinum-based therapies may result in AKI. The standard method of examining kidney tissue may not provide sufficient information about the effects of these drugs on the kidneys. To address this issue, we recommend incorporating an assessment of the analysis of the expression of PDL1 and p53. This personalized approach will help identify the best treatment option for the patient while ensuring the best possible cancer treatment plan.

BACKGROUND: There are multiple neoadjuvant regimens, including platinum agents for triple-negative breast cancer (TNBC), each with a different safety profile, outcome, and pathologic complete response rate (pCR%). We performed a systematic review and network meta-analysis to compare the efficacy and safety of different platinum-based neoadjuvant CT treatments for TNBC.
METHODS: Bibliographic databases (PubMed, Embase, and Cochrane Library) were searched from their inception to October 31, 2022. Eligible studies were randomized clinical trials that evaluated the addition of carboplatin or cisplatin to standard neoadjuvant CT for TNBC. The primary endpoints were pCR rates and DFS/EFS, while the secondary endpoints were grade (G)3-4 hematological toxicity and OS.
RESULTS: Thirteen trials involving 3154 patients comparing six treatments (carboplatin AUC 5, carboplatin AUC 6, carboplatin AUC 2, carboplatin AUC 1.5, cisplatin 75 mg/m2, and standard anthracycline-and/or taxane-based CT) were identified. Based on the most effective treatments added to neoadjuvant CT, carboplatin AUC 2 was associated with the least improvement in pCR% (RR, 1.49; 95%CI, 1.23, 1.8), carboplatin AUC 6 was associated with similar improvement in pCR% (RR 1.58, 95%CI, 1.35, 1.84) and carboplatin AUC 5 with the highest improvement in pCR% (RR 2.23, 95%CI, 1.6,32). The treatment associated with the most considerable improvement in DFS when added to neoadjuvant CT was carboplatin AUC 5 (HR 0.36, 95%CI 0.18, 0.73). It was also better than AUC 6 and AUC 2 (HR= 0.45, 95%CI 0.21-0.96 and HR=0.48, 95%CI 0.23-0.98). All schedules exhibited similar outcomes in terms of OS; however, only AUC 2 demonstrated a significant improvement compared to the no-platinum arms. Neutropenia, thrombocytopenia, and anemia G3-4 were significantly increased by carboplatin AUC 6.
CONCLUSIONS: Based on this network meta-analysis, carboplatin AUC 5 added to standard neoadjuvant CT may provide substantial pCR and DFS benefits with a low toxicity risk compared to other carboplatin doses.

Ovarian cancer, being one of the prevalent gynecological cancers, warrants a therapy that\'s both effective and well tolerated. After extensive drug testing, combination regimens with paclitaxel plus platinum-based agents such as cisplatin/carboplatin and taxanes, have shown promising results for advanced ovarian cancer. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the efficacy of two treatment regimens for advanced ovarian cancer: cisplatin/paclitaxel and carboplatin/paclitaxel.  PubMed (Medline), Science Direct, and Cochrane Library were searched from inception to March 2023. The meta-analysis included patients with histologically verified International Federation of Gynaecology and Obstetrics (FIGO) stages IIB to IV ovarian carcinoma who received either carboplatin/paclitaxel or cisplatin/paclitaxel. The primary outcomes were progression-free survival (PFS), overall survival (OS), quality of life (QOL), complete response rate (CRR), and partial response rate (PRR). The revised Cochrane Risk of Bias Tool 2.0 was used to assess the quality of the RCTs The five RCTs chosen for this statistical analysis consisted of a total of 2239 participants, with 1109 receiving paclitaxel/cisplatin for treatment and the remaining 1130 receiving carboplatin/paclitaxel. Among all included outcomes, these reported significant findings: QoL (p-value=0.0002), thrombocytopenia (p=<0.00001), neurological toxicity (p-value=0.003), nausea/vomiting (p-value=<0.00001), myalgia/arthralgia (p-value=0.02), and febrile neutropenia (p-value=0.01). We concluded that the carboplatin/paclitaxel doublet endows a better quality of life (QOL) to patients along with significantly fewer gastrointestinal and neurological toxicities when compared with the cisplatin/paclitaxel combination. However, the myelosuppressive effects of carboplatin/paclitaxel remain a point of concern and may require clinical management.

BACKGROUND: Paclitaxel and carboplatin is the standard chemotherapy for the treatment of advanced or recurrent endometrial cancer. However, the benefit of adding programmed cell death 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors to chemotherapy is still unclear.
METHODS: We searched PubMed, Scopus, Cochrane, and Web of Science databases for randomized controlled trials that investigated PD-1/PD-L1 inhibitors plus carboplatin and paclitaxel compared with carboplatin and paclitaxel in primary advanced or recurrent endometrial cancer. We computed hazard ratios (HRs) or risk ratios (RRs) for binary endpoints, with 95% confidence intervals (CIs). We used DerSimonian and Laird random-effect models for all endpoints. Heterogeneity was assessed using I2 statistics. R, version 4.2.3, was used for statistical analyses.
RESULTS: A total of three studies and 1,431 patients were included. Compared with carboplatin plus paclitaxel-based chemotherapy, progression-free survival (PFS) rate (HR 0.32; 95% CI 0.23-0.44; p < 0.001) and overall survival (OS) at 30 months (RR 3.13; 95% CI 1.26-7.78; p = 0.01) were significant in favor of the PD-1/PD-L1 inhibitors plus carboplatin and paclitaxel group in the mismatch repair-deficient subgroup. However, there were no significant differences in the mismatch repair-proficient subgroup for PFS (HR 0.74; 95% CI 0.50-1.08; p = 0.117) or OS at 30 months (RR 2.24; 95% CI 0.79-6.39; p = 0.13).
CONCLUSIONS: Immunotherapy plus carboplatin-paclitaxel increased significantly PFS and OS among patients with advanced or recurrent endometrial cancer, with a significant benefit in the mismatch repair-deficient and high microsatellite instability population.

OBJECTIVE: Ototoxicity is a common disabling side effect of platinum-based chemotherapy. This study aimed to assess the evidence on the management of platinum-induced ototoxicity in adult cancer patients.
METHODS: Four databases were searched up to 1 November 2022. Original studies were included if they reported on a pharmacologic or non-pharmacologic intervention to prevent or treat platinum ototoxicity in adults. The articles\' quality was assessed via two grading scales.
RESULTS: Nineteen randomised controlled trials and five quasi-experimental studies with 1673 patients were analysed. Eleven interventions were identified, nine pharmacological and two non-pharmacological. Six of the interventions (sodium thiosulphate, corticoids, sertraline, statins, multivitamins and D-methionine) showed mild benefits in preventing cisplatin-induced ototoxicity. Only one trial assessed corticoids as a potential treatment. Overall, only six trials were deemed with a low risk of bias. The majority of studies inadequately documented intervention-related adverse effects, thereby limiting safety conclusions.
CONCLUSIONS: Current interventions have mild benefits in preventing cisplatin-induced ototoxicity in adult cancer patients. Sodium thiosulphate is the most promising intervention as a preventive strategy. Rigorous, high-quality research is warranted, encompassing an evaluation of all potential symptoms and innovative treatment modalities.

Tumors of various sizes and locations can create a treatment dilemma in achieving adequate surgical margins when sufficient free tissue is not available for closure. Extravascular local adjunctive chemotherapy has been investigated clinically to aid in achieving local tumor control in animals with naturally occurring neoplastic disease. Local chemotherapy can be an alternative primary or a local adjunctive treatment.
This is a summary of relevant findings of in vitro and in vivo studies on local chemotherapeutic delivery through carrier media, together with a summary of outcomes of clinical use of local delivery of chemotherapeutic agents in small animals and Equidae. Literature from 1990 to 2022 was evaluated via searches of PubMed, Google Scholar, and CAB Abstracts databases for studies of local extravascular delivery of chemotherapeutic agents and chemotherapeutic-impregnated delivery systems in research and clinical settings in veterinary medicine.
Chemotherapeutic-impregnated calcium sulfate hemihydrate beads with carboplatin are currently favored for extravascular delivery and are associated with minimal wound complications. The ideal delivery system may vary depending on the chemotherapeutic agent used, commercial availability, targeted tumor type, and location.
Future investigations might focus on the required dose, the rate of sustained release, and enhancing nodal uptake.
Examen des systèmes d’administration extravasculaire locaux d’agents chimiothérapeutiques chez les petits animaux et les chevaux.
Des tumeurs de tailles et emplacements différents peuvent créer un dilemme thérapeutique pour obtenir des marges chirurgicales adéquates lorsqu’il n’y a pas suffisamment de tissu libre disponible pour la fermeture. La chimiothérapie d’appoint extravasculaire locale a été étudiée cliniquement pour aider à obtenir une limitation locale de la tumeur chez les animaux atteints d’une maladie néoplasique naturelle. La chimiothérapie locale peut être une alternative primaire ou un traitement local d’appoint.
Il s’agit d’un résumé des résultats pertinents d’études in vitro et in vivo sur l’administration locale de chimiothérapie par le biais de transporteurs, ainsi que d’un résumé des résultats de l’utilisation clinique de l’administration locale d’agents chimiothérapeutiques chez les petits animaux et les équidés. La littérature de 1990 à 2022 a été évaluée via des recherches dans les bases de données PubMed, Google Scholar et CAB Abstracts pour des études sur l’administration extravasculaire locale d’agents chimiothérapeutiques et de systèmes d’administration chimiothérapeutiques imprégnés dans des contextes de recherche et cliniques en médecine vétérinaire.
Les billes de sulfate de calcium hémihydratée chimiothérapeutique imprégnées de carboplatine sont actuellement privilégiées pour l’administration extravasculaire et sont associées à des complications minimes des plaies. Le système d’administration idéal peut varier en fonction de l’agent chimiothérapeutique utilisé, de la disponibilité commerciale, du type de tumeur ciblé et de l’emplacement.
Les recherches futures pourraient se concentrer sur la dose requise, le taux de libération prolongée et l’amélioration de l’absorption nodale.(Traduit par Dr Serge Messier).

BACKGROUND: The locally advanced cervical cancer (LACC) of FIGO stage IB3-IIA2 is characterized by large local mass, poor prognosis and survival rate. Tumor response to neoadjuvant chemotherapy for LACC, utilized as a surrogate endpoint, is urgently needed to improve. Given that the antitumor immune response can be suppressed by programed death-1 axis, the treatment paradigm of neoadjuvant chemotherapy combined with immunotherapy has been explored as one of the prognostic treatments in a variety of solid carcinoma. So far, the application of sintilimab, a domestic immune checkpoint inhibitor, combined with neoadjuvant chemotherapy is still limited in LACC, especially in large lesions.
METHODS: We present three postmenopausal women diagnosed with FIGO stage IB3-IIA2 cervical squamous cell carcinoma with lesions larger than 5 cm. Demographic, clinical, histopathological, laboratory and imaging data were record. At the completion of the neoadjuvant therapy with paclitaxel plus carboplatin combined with sintilimab, all patients underwent hysterectomy. After neoadjuvant treatment, a pathologic complete response in case 1 and partial responses in case 2 and case 3 were achieved, and neither patient showed any relapse during the follow-up period of 16 to 22 months.
CONCLUSIONS: This report provide evidence to support the combination of sintilimab with neoadjuvant chemotherapy in cervical cancer, which has yet to be validated in prospective studies. More clinical data are needed to verify the effectiveness of the combined regimens. This literature review also collected studies involving potential predictors of response to NACT and immunotherapy, which would be helpful in stratifying patients for future trials.

BACKGROUND: Testing for mutations in Breast Cancer Gene 1/2 (BRCA) has emerged as a novel decision-making tool for clinicians. Patients with metastatic castration-resistant prostate cancer (mCRPC) harboring pathogenic BRCA mutations can benefit from poly (ADP-ribose) polymerase inhibitor (PARPi) and platinum treatments, whereas the impact of the mutation on sensitivity to cabazitaxel and prostate-specific membrane antigen (PSMA)-ligand therapy is currently unknown.
OBJECTIVE: To assess the efficacy of PARPi, platinum, cabazitaxel, and PSMA-ligand therapies in BRCA-positive mCRPC.
METHODS: Databases were queried in February 2022. We performed data synthesis by using both proportional and individual patient data. For prostate-specific antigen (PSA) response rate (≥50% decrease from baseline [PSA50]) evaluation, we pooled event rates with 95% confidence intervals (CIs). Progression-free (PFS) and overall (OS) survival analyses with individual patient data were performed with the mixed-effect Cox proportional hazard model and single-arm random-effect analysis, providing pooled medians.
RESULTS: We included 23 eligible studies with 901 BRCA-positive mCRPC patients. PSA50 response rates for PARPi and platinum were 69% (CI: 53-82%), and 74% (CI: 49-90%), respectively. Analyses of OS data showed no difference between PARPi and platinum treatments (hazard ratio: 0.86; CI: 0.49-1.52; p = 0.6). The single-arm OS and PFS analyses revealed similarities among different PARPis; pooled PFS and OS medians were 9.7 mo (CI: 8.1-12.5) and 17.4 mo (CI: 12.7-20.1), respectively.
CONCLUSIONS: Our data revealed that different PARPis were similarly effective in terms of PFS and OS. Moreover, we found that PARPi and platinum therapy were comparable in terms of PSA50 response rate and OS, highlighting that platinum is a valid treatment option for BRCA-positive mCRPC patients. However, prospective interventional studies comparing these agents are essential to provide a higher level of evidence.
RESULTS: In this report, we found that different poly (ADP-ribose) polymerase inhibitors had similar efficacy, and platinum was a valid treatment option in BRCA-positive metastatic castration-resistant prostate cancer patients.
