NUT midline carcinoma as a primary lung tumor treated with anlotinib combined with palliative radiotherapy: a case report

Background NUT (nuclear protein in testis) midline carcinoma (NMC) is a rapidly progressive tumor arising from midline structures. Recent cases have reported that the poor prognosis with a median survival of 6.7 months and a 2 years overall survival of 19% due to limited treatment. Based on the effect of arotinib on inhibiting tumor growth and angiogenesis. We present one patient case treated with anlotinib and radiotherapy. Case presentation Here, we describe a 33-year old patient who complained of cough and chest pain and was diagnosed as a pulmonary NMC through CT scan, FISH and immunohistochemistry. In addition, we initially demonstrated that anlotinib combined with palliative radiotherapy could significantly prevent the tumor growth in a pulmonary NMC. Conclusion The report indicated that anlotinib combined with palliative radiotherapy could inhibit the tumor progression in a pulmonary NMC, which may provide a combined therapy to pulmonary NMC in the future.

Palliative Radiotherapy for Gastric Cancer Bleeding: A Multi-Institutional Retrospective Study.

Background: Palliative radiotherapy for gastric cancer bleeding has been reported to be a safe and effective treatment, but predictive factors for achievement of hemostasis and overall survival have not been established.Methods: In this retrospective study, 120 courses of palliative radiotherapy for gastric cancer bleeding in 117 patients in 4 institutes in Japan were reviewed with approval of the ethical committee in each institute. The rate of achieving hemostasis was evaluated by 50% or more reduction of red blood cell transfusion before and after the start of radiotherapy, elevation of blood hemoglobin concentration in a period of 4 weeks from the start of radiotherapy or improvement of subjective or objective clinical symptoms in a period of 4 weeks from the start of radiotherapy. Predictive factors for overall survival and achieving hemostasis were investigated with the Cox hazards model.Results: The median overall survival period was 3.7 months. Multivariate analysis showed that absence of metastatic disease, higher biological effective dose, higher serum albumin level, lower blood urea nitrogen level and lower neutrophil-to-lymphocyte ratio (NLR) were associated with longer overall survival. Elevation of hemoglobin concentration in a period of 4 weeks from the start of radiotherapy (mean concentration: 8.2 g/dL vs. 8.9 g/dL, p=0.006) and decrease in the amount of red cell transfusion from a 4-week period before to a 4-week period after the start of radiotherapy (mean amount: 716 mL vs. 230 mL, p<0.0001) were observed. The overall rate of achievement of hemostasis was 59.6%. In multivariate analysis, higher biological effective dose was associated with achievement of hemostasis. Grade 2 or higher acute adverse effects related to radiotherapy were observed in 17.5% of cases in 120 treatment courses. Six cases (5.0%) had grade 3 or 4 adverse effects including gastric penetration in 1 patient and anorexia requiring total parental nutrition in 3 patients. No grade 5 adverse effects were observed.Conclusions: Palliative radiotherapy for gastric cancer bleeding seems to be an effective and safe treatment strategy. Higher treatment dose was associated with longer overall survival and a hemostatic effect. Some hematological parameters may predict overall survival, and they would be helpful for deciding the treatment strategy.

What Did the Pandemic Teach Us About Palliative Radiation in Head and Neck Cancer?

Aim: To assess the feasibility and efficacy of palliative radiotherapy dose regimens for patients with locally advanced head and neck cancer. Methods: Fifty patients of previously untreated, inoperable, stage IVA and IVB squamous cell carcinoma of the head and neck, deemed unfit for radical treatment, were included in the study from May 2020 to June 2020. Two palliative radiotherapy regimens were used. First was a single fraction radiation with 8 Gy for patients with limited life expectancy and poor performance status, which was repeated after 4 weeks in case of good symptom relief. The second regimen was used for patients with good performance status and consisted of fractionated radiation with 30 Gy in 10 fractions over 2 weeks, which was followed by supplementary radiation with 25 Gy in 10 fractions over 2 weeks in patients with good symptomatic response at 2 weeks. Symptoms were assessed at baseline and at the end of 4 weeks after treatment completion using the numerical rating score. Patients were followed up for a median of 4.5 months and assessed for symptom control and overall survival. Results: Forty-eight patients completed treatment and were included for analysis. Of the 24 patients who received single fraction radiation, 13 (54.2%) were given the second dose. Improvement in pain and dysphagia were reported in 57.9% and 60% patients, respectively. A total of 55.5% noted decrease in size of the neck node. Twenty-four patients received fractionated radiation and 15 (62.5%) were given the second course after 2 weeks. Relief in pain and dysphagia was reported in 68.2% and 63.6% patients, respectively. There were no grade 3/4 toxicities. Symptom control lasted for at least 3 months in 30% of the patients who received single fraction radiation and 54.2% of the patients who received fractionated radiation. The estimated 6-month overall survival of the entire cohort was 51.4%. Conclusion: Judicious use of palliative radiation in advanced incurable head and neck cancers provides effective and durable symptom relief and should be used after careful consideration of patient prognosis, logistics of treatment, and goals of care.
