[A Case of Hepatocellular Carcinoma Relapse in the Lungs 17 Years after Liver Resection].

A 77-year-old man underwent a right hemihepatectomy for hepatocellular carcinoma in 2002. The patient remained alive without recurrence for 17 years after surgery. In September 2019, he was diagnosed with a tumor in the lower lobe of the right lung by follow-up CT.

[A Case of Laparoscopic Surgery for Malignant Lymphoma of the Small Intestine with Bowel Obstruction].

An 80-year-old woman presented to our hospital complaining of nausea and abdominal distention. An abdominal computed tomography scan revealed wall thickening of the small intestine, a dilated oral intestinal tract, swollen intra-abdominal lymph nodes, and splenomegaly. Moreover, the soluble interleukin-2 receptor level was increased at 2,120 U/mL.

A case of pancreatic PEComa with prominent inflammatory cell infiltration: the inflammatory subtype is a distinct histologic group of PEComa.

Background: PEComa is a mesenchymal tumor that can occur in various organs including the uterus and soft tissues. PEComas are composed of perivascular epithelioid cells, and angiomyolipoma (AML), clear cell sugar tumor (CCST), and lymphangiomyomatosis (LAM) are considered lesions of the same lineage as tumors of the PEComa family. Histologically, a common PEComa shows solid or sheet-like proliferation of epithelioid cells.

[A Case of Gastric Cancer with Pulmonary Carcinomatous Lymphangitis and Disseminated Carcinomatosis of the Bone Marrow Responding to S-1 plus Cisplatin Chemotherapy].

A 63-year-old man was admitted to a hospital owing to shortness of breath. He was diagnosed as having gastric cancer with pulmonary carcinomatous lymphangitis(PCL)and disseminated carcinomatosis of the bone marrow(DCBM). Regarding tumor markers, carcinoembryonic antigen(CEA)and carbohydrate antigen 19-9(CA19-9)levels increased to 332 ng/ mL and 921 U/mL, respectively.

Phase II trial of induction chemotherapy with carboplatin and paclitaxel plus bevacizumab in patients with stage IIIA to IV nonsquamous non-small cell lung cancer.

Purpose: Surgery remains the best curative treatment option for non-small cell lung cancer (NSCLC), but is of benefit only to patients with localized disease. A meta-analysis showed a significant beneficial effect of induction chemotherapy on survival, but there is still no clear evidence. This phase II study was conducted to establish whether induction chemotherapy with carboplatin (CBDCA) and paclitaxel (PTX) plus bevacizumab prior to surgery reduces the risk of progression.

The Real-world Efficacy and Safety of Ombitasvir/Paritaprevir/Ritonavir for Hepatitis C Genotype 1.

Objective There are few reports on the outcomes of 12-week paritaprevir, ombitasvir, and ritonavir (PTV/OBV/r) treatment in real-world clinical settings. We aimed to evaluate the efficacy and safety of 12-week treatment with ritonavir-boosted paritaprevir and ombitasvir in patients with hepatitis C virus (HCV) genotype 1 infection in a real-world setting. Methods Fifty-eight patients with chronic hepatitis or compensated hepatic cirrhosis and genotype-1 HCV infection were treated with PTV/OBV/r and followed for 24 weeks after the completion of treatment in 10 centers in northern Tohoku.

Successful local control of recurrent penile cancer treated with a combination of systemic chemotherapy, irradiation, and mohs' paste: a case report.

Penile squamous cell carcinoma (pSCC) is a rare disease, making it difficult to establish a standard of care, particularly in the advanced stage. We report a case of pSCC with advanced lymph node metastasis treated with multimodal therapy consisting of combination chemotherapy, irradiation, and chemosurgery using Mohs' zinc chloride-containing paste. An 80-year-old male with a past history of local treatment for penile cancer presented with a large painful inguinal mass with an ulcer and exudates.
