Pulmonary pleomorphic carcinoma is an uncommon malignant tumor of the lung, which has the dual cell components of spindle or giant cells and epithelial cells. The objective of this study was to investigate the clinical course and efficacy of palliative chemotherapy in patients with advanced pulmonary pleomorphic carcinoma. Twelve patients were diagnosed with advanced pulmonary pleomorphic carcinoma and received palliative chemotherapy from February 2000 to December 2007. Among the 12 patients, five patients received gemcitabine/cisplatin, three patients received gemcitabine/carboplatin, two patients received paclitaxel/carboplatin, one patient received paclitaxel/cisplatin, and one patient received docetaxel/cisplatin as first-line chemotherapy. The median patient's age was 62 (range, 32-72 years). Among the 12 patients, nine patients had relapsed disease after curative resection and three patients had metastatic disease at the initial presentation. After treatment with first-line palliative chemotherapy, seven patients (58%) had progressive disease, three patients (25%) had stable disease, and only two patients (17%) had a partial response. The median overall survival from the day of initiation of first-line chemotherapy was only 8 months (95% CI, 6-10) with median follow-up of 26 months. These results showed the dismal prognosis and the poor response to chemotherapy of advanced pulmonary pleomorphic carcinoma. Further studies are needed to investigate whether the current strategy of palliative chemotherapy for the treatment of advanced pulmonary pleomorphic carcinoma can be justified or not. Moreover, additional novel treatment approaches are required.

A 55-year-old man with tuberous sclerosis complex (TSC) was diagnosed with left renal angiomyolipoma (AML), a group of perivascular epithelioid cell tumors called PEComas. He had received the mTOR inhibitor everolimus, which resulted in a complete response. However, a left renal mass relapsed in two years, followed by the occurrence of a hepatic mass five months later.

Background: Dual inhibition of cytotoxic T-lymphocyte associated protein 4 (CTLA-4) and programmed death ligand 1 (PD-L1) has been shown to be an effective treatment strategy in many cancers. We sought to determine the objective response rate of combination durvalumab (D) plus tremelimumab (TM) in parallel cohorts of patients with carefully selected rare cancer types in which these agents had not previously been evaluated in phase II trials and for which there was clinical or biological rationale for dual immune checkpoint inhibitor therapy to be active.
Methods: We designed a multi-centre, non-blinded, open-label phase II basket trial with each of the following 8 rare cancers considered a separate phase II trial: salivary carcinoma, carcinoma of unknown primary (CUP) with tumour infiltrating lymphocytes and/or expressing PD-L1, mucosal melanoma, acral melanoma, osteosarcoma, undifferentiated pleomorphic sarcoma, clear cell carcinoma of the ovary (CCCO) or squamous cell carcinoma of the anal canal (SCCA).

Background: Soft-tissue sarcoma involving the popliteal fossa remains challenging because it is difficult to achieve wide margins with limb salvage in this location. Adjuvant therapy is frequently necessary, and limb function can be adversely affected. We reviewed our experience with these tumors.

A chest CT scan showed a mass shadow with a cavitary lesion in segment 6 of the right lung.

Undifferentiated pleomorphic sarcoma, an exceedingly rare and aggressive primary cardiac tumor arising from mesenchymal stem cells, is associated with poor prognosis and high mortality despite adequate treatment. A 52-year-old female presented with a 2-month history of angina and dyspnea on exertion. Her clinical history included severe acute respiratory syndrome coronavirus 2 myocarditis and iron deficiency anemia.
