MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. [37] Crizotinib and entrectinib are approved for use in patients with NSCLC with ROS1 rearrangements, with the latter appearing to have greater activity against intracranial disease. The pooled estimates of sensitivity and specificity of CT scanning for identifying mediastinal lymph node metastasis were 51% (95% CI, 47%54%) for sensitivity and 86% (95% CI, 84%88%) for specificity.

Among 11 patients with measurable CNS disease, the objective intracranial response was 91%, including 27% complete responses. Although different multifraction regimens appear to provide similar symptom relief,[, Evidence of a modest increase in survival in patients with better performance status given high-dose radiation therapy is available.[. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapies before receiving pembrolizumab (see the FDA label for pembrolizumab). Gainor JF, Curigliano G, Kim DW, et al. This study showed ultra-brief pulses produced less cognitive side effects as well as similar rates of efficacy. Cecil KM, Hills EC, Sandel ME, Smith DH, McIntosh TK, Mannon LJ, et al.

Grade 3 treatment-related diarrhea and stomatitis occurred more frequently with afatinib; however, grade 3 rash or acne were more common in patients who received erlotinib. The histological type of NSCLC correlates with site of origin, reflecting the variation in respiratory tract epithelium of the bronchi to alveoli. Negative 18F-FDG PET scanning does not preclude biopsy of radiographically enlarged mediastinal lymph nodes.

Adjuvant targeted therapy with osimertinib for patients with EGFR-mutated NSCLC and resected stage IB NSCLC was studied in a phase III clinical trial and was found to significantly increase DFS. Maintenance therapy following first-line chemotherapy. Beam-hardening effects, displacement of the CT signal near metal objects, bone, calcifications, and high concentrations of contrast, can degrade the image quality and prevent accurate assessment. [, Another randomized, phase III trial investigated the efficacy and safety of cisplatin-gemcitabine plus bevacizumab.[. Thus, there is no clear benefit in radiation dose escalation beyond 60 Gy for stage III NSCLC. was noted with lobectomy for patients with tumors larger than 3 cm Pathological complete response or minimal microscopic disease was seen in 61 (56%) resection specimens. On the basis of meta-analyses of the trials, the following conclusions can be drawn: Among the active combinations, definitive recommendations regarding drug dose and schedule cannot be made, with the exception of carboplatin, pemetrexed, and pembrolizumab for patients with nonsquamous tumor histology. but not for those with tumors smaller than 3 cm. The overall response rate was 72% (95% CI, 58%84%). With a median follow-up of 32.9 months, the median OS was 40.7 months, and 2-year local tumor control was 95%. If your doctor is sending you in for brain imaging, remember that this is a non-invasive procedure that will help your doctor have a clearer understanding of how your brain is functioning. Current evidence suggests that lung cancer resection combined with complete ipsilateral mediastinal lymph node dissection (CMLND) is not associated with improvement in survival compared with lung cancer resection combined with systematic sampling of mediastinal lymph nodes in patients with stage I, II, or IIIA NSCLC. [20-22][Level of evidence C2] Survival benefit may be greater in patients with EGFR protein expression by immunohistochemistry or increased EGFR gene copy number by fluorescence in situ hybridization studies (FISH),[21,22] but the clinical utility of EGFR testing by immunohistochemistry has been questioned.[23].
