Idiopathic interstitial pneumonias (IIPs) are among the most common complications in patients with lung cancer. In such patients with cancer, the most serious expression of toxicity in Japan is acute exacerbation of IIPs caused by anticancer treatment. Nevertheless, there has been no consensus and no evidence presented, regarding optimal treatment for advanced lung cancer with IIP. ⋯ This is the first report indicating that patients with advanced SCLC with IIPs may benefit from chemotherapy. Patients with advanced SCLC with IIP treated with etoposide and carboplatin combination chemotherapy gain benefits, with safety equivalent to that seen in patients without IIP. The results from this study would support, on ethical grounds, the conduct of a large-scale study to evaluate this regimen.

Prophylactic cranial irradiation has recently been reported to improve overall survival and quality of life in patients with extensive-stage small cell lung cancer. The generalizability of this treatment to an unselected population with extensive-stage small cell lung cancer is not clear, as the incidence of brain metastases is variably reported in the literature, ranging from 25 to 60%. ⋯ 20.8% of patients developed brain metastases after their initial presentation. This incidence is lower than that previously reported and may suggest that prophylactic cranial irradiation should be targeted to patients at highest risk. Response to chemotherapy and less than 5 kg baseline weight loss were independent predictors of future brain metastases.

Screening-detected lung cancers: is systematic nodal dissection always essential?
To address whether systematic lymph node dissection is always necessary in early lung cancer, we identified factors predicting nodal involvement in a screening series and applied them to nonscreening-detected cancers. ⋯ This limited experience suggests that in early-stage clinically N0 lung cancers with maxSUV <2.0 or pathological nodule size ≤10 mm, systematic nodal dissection can be avoided as the risk of nodal involvement is very low.

In recent years, there have been significant advances in the management of patients with lung cancer. This progress is associated with increased use of medical intensive care units (ICUs) for the management of a variety of complications related to cancer, its treatment, or comorbid illnesses. At the same time, there are advances in the care of critically ill patients in general. ⋯ However, it is clear that not all lung cancer patients will benefit from this aggressive care. Although there are no absolute predictors, the current evidence suggests that advanced refractory cancer, poor baseline performance status, the need for mechanical ventilation, and multiple organ system failures are factors associated with worse ICU outcome. Further studies are needed to better triage patients who are going to benefit from ICU care; determine the optimal duration of this care; and assess the impact of this therapy on the long-term survival, cancer treatment, and quality of life of these patients.
