Introduction Immune checkpoint inhibitors have improved clinical outcomes in a wide range of cancers. While skin toxicity is not uncommon with immune checkpoint inhibitors, generalized nail discoloration has not been reported with their use in oncology. Case report Herein, we report a unique case of bluish-gray fingernail discoloration due to nivolumab therapy for relapsed melanoma. Management and outcome: This condition reversed completely 10 weeks after nivolumab discontinuation. Naranjo nomogram assessment renders the causality relationship between nivolumab and nail discoloration probable. Discussion To our knowledge, this is the first case report of an unusual bluish-gray nail discoloration due to therapy with nivolumab. The mechanism by which nivolumab causes this side effect remains to be elucidated.
Introduction Clinical indications of immune checkpoint inhibitors have expanded to a variety of malignancies. Approximately one in six patients with hepatocellular carcinoma respond to programmed death 1 inhibitors nivolumab and pembrolizumab. Case report We report herein a patient with synchronous metastatic hepatocellular carcinoma and advanced papillary thyroid carcinoma treated with nivolumab in the second-line therapy. Management and outcome: The hepatocellular carcinoma showed a durable response to the second-line agent nivolumab. Remarkably, the patient’s papillary thyroid carcinoma also responded to this programmed death 1 inhibitor. Discussion To our knowledge, this is the first case report showing the efficacy of nivolumab in the treatment of metastatic papillary thyroid carcinoma. Further studies with immune checkpoint inhibitors in papillary thyroid carcinoma seem warranted.
Malignant mixed Müllerian tumor remains an important contributor to morbidity and mortality in women with uterine cancer. Surgery is the primary treatment modality, followed by chemotherapy and/or radiation for advanced disease or high-risk patients. Clinico-epidemiologic characteristics and outcomes in older versus younger women with Malignant mixed Müllerian tumor may differ. We analyzed and now report on 15 consecutive patients with uterine Malignant mixed Müllerian tumor treated at our institution from 2000 to 2018. The mean age at diagnosis was 65 years; 60% (9/15) patients were overweight/obese. Forty-six percent (7/15) had hypercholesterolemia, an association not previously linked with Malignant mixed Müllerian tumor in the literature. All patients but one had surgical excision of the tumor. A third of patients received adjuvant radiation therapy. A majority of patients received chemotherapy; the preferred regimen was carboplatin-paclitaxel. The patients older than 70 had a tendency towards a more advanced disease stage at diagnosis and a significantly shorter cancer-specific survival than their younger counterparts (6 months vs. 102 months (hazard ratio 1.32, p = 0.02)). Our study's conclusions are restricted due to its relatively small size, retrospective design, and some variation in the chemotherapy doses administered in individual patients. Larger studies are needed to confirm the significance of our findings.
Background Although now available in oncology clinics, comprehensive germline mutation testing is being performed only in a minority of patients with advanced uterine papillary serous cancer (UPSC). Some of these patients might harbor various targetable mutations, either heritable or acquired. Data sources: We conducted a retrospective cohort study involving all consecutive patients with UPSC treated at our institution from 2009-2019. Data on epidemiology, with an accent on personal and family history of cancer, clinical presentation, disease stage, employed treatment modalities and cancer-specific survival (CSS) was sought. Findings Thirteen patients were seventy years of age or younger (≤70) while 15 were older than seventy (>70), and the two arbitrary patient cohorts were well-balanced for the TNM stage. Four UPSC patients >70 had a personal history of metachronous breast cancer. We also identified five cases of breast cancer, two cases of colon cancer, and one of each ovarian and uterine cancer in the first-degree relatives of UPSC patients >70. More than 90% of patients had surgical excision/debulking, and nearly half of the patients in each group received systemic chemotherapy. The most common chemotherapy regimen was carboplatin-paclitaxel every three weeks. Compared to patients ≤70, the UPSC patients >70 were less likely to undergo postoperative radiation therapy (6% vs 61.5%; p = 0.001) and had a worse CSS (21.8 vs. 27.4 months; HR 0.61, p = 0.03). Conclusions Personal and family history in a cohort of older UPSC patients identified an excess of second primary cancers, and these patients displayed a shorter CSS. Comprehensive germline and tumor mutation analysis might identify optimal candidates for various targeted agents and immune checkpoint inhibitors, and ultimately improve survival. This may represent an unmet need in the UPSC patients, and further studies are needed to confirm the significance of our findings.
