Objective We identified the prognostic relevance of pneumothorax in interstitial lung disease (ILD) patients and evaluated the efficacy and safety of autologous blood-patch pleurodesis. Methods We retrospectively reviewed 59 occurrences of pneumothorax in 34 ILD patients identified over a 12-year period. Results Air leakage ceased in 16 of 22 (72.7%) episodes after blood pleurodesis and in 11 of 14 (78.6%) episodes after chemical pleurodesis. Both the cure ratio and recurrence ratio in the cure episodes were comparable with those in the chemical pleurodesis group (p=0.99 and 0.99, respectively). In addition, there were no harmful events associated with blood pleurodesis. The median survival time after the first episode of pneumothorax was less than 9 months in patients with idiopathic interstitial pneumonia (IIP) and only around 3 years in the patients with other types of ILD, which have essentially favorable outcomes. Kaplan-Meier survival estimates were significantly worse in the patients with concomitant pneumomediastinum than in those without (p<0.05). A multivariate Cox regression analysis identified that the number of episodes of pneumothorax, IIP diagnosis and concomitant pneumomediastinum were independent predictors of death. Conclusion Autologous blood-patch pleurodesis is safe and worth considering as a first-line treatment for pneumothorax secondary to ILD. However, despite treatments, the prognosis after the onset of pneumothorax in ILD patients was found to be poor. In addition, concomitant pneumomediastinum may further worsen the prognosis.

A standard treatment has not yet been established for elderly small-cell lung cancer patients, especially when they have end-stage renal disease. We report the first case of successful chemoradiotherapy in an elderly small-cell lung cancer patient undergoing continuous ambulatory peritoneal dialysis. A 77-year-old Japanese man on continuous ambulatory peritoneal dialysis was diagnosed as having limited disease small-cell lung cancer. He received four monthly cycles of chemotherapy consisting of carboplatin at 240 mg/m2 on day 1 and etoposide at 40 mg/m2 on days 1 and 3. He underwent additional hemodialysis on days 1 and 3, while continuous ambulatory peritoneal dialysis continued as usual on the other days. Following chemotherapy, he underwent hyperfractionated radiotherapy to a total dose of 45 Grey, resulting in complete remission of the disease. A pharmacokinetic study showed an area under the concentration-time curve of carboplatin of 3.41 to 4.88 mg·min/mL, increasing gradually over the first three cycles, while etoposide did not show this gradual increase. The increased area under the concentration-time curve of carboplatin may have reflected a worsened renal function during chemotherapy. Despite dose reductions and favorable areas under the concentration-ime curve of carboplatin, the patient suffered grade 3-4 hematological toxicities, necessitating transfusions and a further dose reduction. The patient died of recurrent small-cell lung cancer 19 months after diagnosis.
