RESUMEN
Tumor lysis syndrome (TLS) is a well-known oncologic emergency. It is a constellation of metabolic derangements usually observed in hematological malignancies due to rapid cell lysis, typically due to chemotherapy or radiotherapy initiation. Spontaneous TLS is an unusual complication in solid malignancies, and only a few cases have previously been reported for spontaneous TLS in gynecological malignancies. We report a case of TLS in a 50-year-old female patient shortly after resection of high-grade uterine sarcoma. We review previous TLS cases in uterine malignancies and the associated morbidity and mortality.
RESUMEN
The role of circulating tumor DNA (ctDNA) is expanding in oncology practices, and it is increasingly being used for targeted therapies and disease monitoring. It is minimally invasive and provides data from both primary and secondary sites of disease. Herein, we report a unique case of a patient with microsatellite instability-high (MSI-H) pancreatic adenocarcinoma (PDAC) treated with neoadjuvant chemotherapy and pembrolizumab who achieved a pathologically confirmed complete resolution of the tumor. A 75-year-old female was diagnosed with pancreatic adenocarcinoma (PDAC) in the uncinate process with aortocaval and retrocrural adenopathy. Next-generation sequencing was obtained via ctDNA testing, and the patient was initiated on cytotoxic chemotherapy while awaiting results. ctDNA revealed MSI-H status, and pembrolizumab was added to the cytotoxic chemotherapy regimen. At follow-up after five cycles of treatment, excellent treatment response was noted on magnetic resonance imaging (MRI) of the abdomen, demonstrating the resolution of the pancreatic mass and adenopathy. Six months of neoadjuvant treatment was given in total, after which the patient underwent resection with curative intent and achieved a complete pathological response with no evidence of disease. The role of ctDNA testing in directing treatment and influencing follow-up has already demonstrated great value. In our case, ctDNA adequately replaced conventional tissue biopsy, alleviating the burden of invasive testing on the patient. This is of great value, especially for patients with non-resectable tumors as well as in several other clinical scenarios. Our case also contributes to the growing body of literature demonstrating the role of immune-directed therapy for MSI-H PDAC.
RESUMEN
BACKGROUND: Compound tincture benzoin (CTB) is used as a post-procedure skin seal antiseptic agent since ancient times; but this drug is reported to cause allergic contact dermatitis and other unwanted side effects. Our aim of the present study was to compare alternative agent like Medicated Adhesive dressing (MAD) with CTB as a post-procedure skin seal dressing. DESIGN: This prospective randomized controlled experimental study included an equal number of patients in MAD and CTB as a post-operative seal dressing material for percutaneous interventions. Both the groups were graded for various efficacy parameters like comfort, applicability, dressing material, and immediate post-operative complications by operating doctor and attending nurse with a maximum 10 points in each group. RESULTS: 120 patients were studied in each MAD and CTB group. Out of total patients 31.25% were males and the mean age of the patient was 33.56 ± 11.10. Allergic contact dermatitis developed in 9 (7.49%) of CTB group and in 1 (0.83%) of MAD group (P < 0.002), while local site skin infections were noted in 8 (6.67%) of CTB group and in 1 (0.83%) of MAD (P < 0.002). Operating doctor graded MAD and CTB to 7.60 ± 0.49 and 3.62 ± 0.48 (P < 0.003); and attending nurse 7.40 ± 0.49 and 3.41 ± 0.49 (P < 0.003) respectively. CONCLUSION: MAD is a safe, efficient and non-inferior alternative dressing material for post-procedure skin incision seal in comparison to CTB.
