A patient with ALK-positive lung adenocarcinoma who survived alectinib-refractory postoperative recurrence for 4 years by switching to ceritinib.

Echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) rearrangements are found in ~ 5% of patients with non-small cell lung cancer (NSCLC). Several tyrosine kinase inhibitors (TKIs) have been developed for treatment of so-called ALK-positive NSCLC. In cases of tumor progression during treatment with second-generation ALK-TKIs, such as alectinib, brigatinib, or ceritinib, National Comprehensive Cancer Network guidelines propose a switch to lorlatinib, a third-generation ALK-TKI, or to cytotoxic chemotherapy. However, they do not mention switching to other second-generation ALK-TKIs. Here, we present a rare case of a 53-year-old Japanese woman, who had never smoked, with ALK-positive lung adenocarcinoma who survived alectinib-resistant postoperative recurrence for 4 years by switching to ceritinib. She underwent curative resection for lung adenocarcinoma, but the cancer recurred at the bronchial stump and mediastinal lymph nodes. After platinum-doublet chemotherapy, the patient still had a single growing liver metastasis, but the tumor was found to harbor EML4-ALK rearrangement. Therefore, the patient started to take ALK-TKIs. Alectinib was the second ALK-TKI used to treat this patient. Alectinib shrank the liver metastasis, which was surgically resected. The tumor relapsed again during continued treatment with alectinib, which was switched to ceritinib. Ceritinib was effective for the relapsed tumor and treatment continued well for 4 years. This case report suggests that, in case of tumor progression during treatment with a second-generation ALK-TKI, switching to another second-generation ALK-TKI may be one of the treatment options. Further analyses are warranted to find robust markers to determine which ALK-TKI is best for each patient.

The efficacy of the Kampo medicine rikkunshito for chemotherapy-induced anorexia (RICH trial): study protocol for a randomized controlled trial.

BACKGROUND: Cisplatin is a key drug in lung cancer therapy. However, cisplatin is also well known to induce gastrointestinal disorders, such as chemotherapy-induced nausea and vomiting, anorexia, and weight loss. These symptoms sometimes affect patients' quality of life and make continuation of chemotherapy difficult. Anorexia is a cause of concern for patients with cancer because a persistent loss of appetite progresses to cancer cachexia. Although evidence-based management for chemotherapy has recently been established, there is room for improvement. METHODS/DESIGN: This placebo-controlled, double-blind, randomized trial will aim to determine the efficacy of the traditional Japanese Kampo medicine rikkunshito (TJ-43) for preventing anorexia caused by cisplatin-including chemotherapy in patients with lung cancer. Patients with lung cancer who plan to receive cisplatin-including chemotherapy will be recruited. Patients who provide written consent will be randomly allocated to receive either TJ-43 (arm A) or placebo (arm B) for one course of chemotherapy (21 or 28 consecutive days). Investigators and patients will be masked to the treatment assignment throughout the trial. The primary endpoint will be evaluated as the change in dietary intake from day 0 (the day before the start of chemotherapy) to day 7 of cisplatin-including chemotherapy. The two arms of the trial will comprise 30 patients each. From November 2014, a total of 60 patients will be recruited, and recruitment for the study is planned to be complete by October 2017. DISCUSSION: This trial is designed to examine the efficacy of rikkunshito (TJ-43) for reducing anorexia and maintaining food intake caused by cisplatin-including chemotherapy in patients with lung cancer. TRIAL REGISTRATION: Japan Pharmaceutical Information Center Clinical Trials Information (JAPIC CTI), trial registration: JAPIC CTI-142747 . Registered on 15 December 2014; the RICH trial.

[Two cases of thymic carcinoid treated with octreotide long-acting repeatable].

Thymic carcinoid is a rare disease that accounts for 3.1% of thymic tumors and 1.8-6% of all carcinoid tumors in Japan. Advanced thymic carcinoid has a 5-year survival rate of 28-31%.Compared with carcinoid tumors that arise in other organs, thyroid carcinoid tumors carry a relatively worse prognosis, and the most effective therapeutic strategy is thought to be surgical resection.However, for patients with recurrence and distant metastases, multimodal therapy including radiotherapy and/or chemotherapy is usually applied.No chemotherapy treatment regimen has been established in Japan, although the National Comprehensive Cancer Network Guidelines proposed the application of octreotide long-acting repeatable(LAR).In this report, we present two cases of thymic carcinoid that were treated with octreotide LAR and achieved long-term survival.
