133 Background: The presence of cachexia at the time of cancer diagnosis and its influence on disease management and treatment outcomes for patients receiving radiotherapy are poorly described. Here, we assess the role of baseline cachexia in patients with NSCLC on first-line treatment modality and clinical outcomes. Methods: Retrospective review of medical records identified 1,334 patients with NSCLC consecutively treated at a tertiary care health system between 1/1/06 and 12/31/13. Cachexia was defined using the well-accepted and validated international consensus definition. The delivery of radiotherapy and its treatment intent were abstracted. Results: The cohort included a representative group of patients with a median age at diagnosis of 64 years, 47% females, and 32% patients of non-White race. Stage at diagnosis was I, II, III, and IV in 291, 105, 356, and 578 (43.3%) patients, respectively. Cachexia was present at the time of diagnosis in 403 (30.2%) patients including 18%, 14%, 32%, and 39% of stage I, II, III, and IV patients, respectively. Palliative intent radiotherapy was received by significantly more stage IV patients with cachexia (74%) than without cachexia (63%) (X2, P = .01). In contrast, baseline cachexia was not associated with curative intent radiotherapy in stage I-III disease. At a median follow-up of 24 months, 857 deaths have been observed. Cachexia at the time of diagnosis was prognostic for worse survival by stage. For patients with stage IV NSCLC, median survival was 11 months for patients without cachexia but 6 months for patients with cachexia at diagnosis (P < .001). Cachexia remained significant in stage I NSCLC, with median survival of 45 and 67 months with or without cachexia at diagnosis, respectively (P = .03). Conclusions: Cancer cachexia at the time of diagnosis is common in patients with NSCLC even with early stage disease. The presence of cachexia at diagnosis is associated with utilization of radiotherapy as a palliative treatment. However, cachexia at diagnosis of NSCLC, even with early stage disease, is prognostic of worse outcomes despite curative intent radiotherapy.

The purpose of this study is to compare the predicted rate of local control and bladder and rectum toxicity rates for image-guided adaptive brachytherapy plans using a tandem and ovoid (T/O) applicator versus using a simulated hybrid intracavitary/interstitial tandem and ring applicator with needles (T/R þ N) for patients with locally advanced cervical cancer (LACC). METHODS AND MATERIALS: Patients with $ FIGO Stage IIB locally advanced cervical cancer treated with T/O from a single institution were included. Simulated treatment plans were created with a T/R þ N applicator for the best high-risk clinical target volume (CTV) coverage and minimal dose to organs at risk. Three-year local control rate was estimated using published dose-volume effect relationships. Next, the high-risk CTV EQD2 D90 of T/R þ N plans were calculated, and bladder and rectum toxicity rates were estimated. Analysis was performed in subpatient groups defined based on tumor volume and ratio of maximal and minimal tumor radii (RR) that reflects tumor shape asymmetry. RESULTS: Improvements in predicted local control rate for the T/R þ N were 0.8, 4.1, 1.6, and 3.9% for groups with tumor volume !35 cc, $35 cc, RR ! 2.0, and $2.0, respectively, with the latter three being statistically significant. Predicted reductions in Grade 2e4 toxicity rates of bladder and rectum were significant in all groups except bladder toxicity in tumor volume ! 35 cc, when T/R þ N plans were normalized to the same CTV coverage as the T/O plans. Comparing unnormalized T/R þ N plans and T/O plans, predicted toxicity reductions were significant in all groups except rectum toxicity in RR $ 2.0. Predicted reduction of toxicity rate was larger for patients with large tumor or large tumor RR, although some reductions were relatively small.

Radiation recall dermatitis (RRD) is a rare complication that occurs after completion of radiation therapy (RT) and initiation of a precipitating agent, most commonly chemotherapeutic medications. Various theories attempt to explain the mechanism, including activation of the body's inflammatory pathways through nonimmune activation. Likewise, radiation-induced organizing pneumonia (RIOP) is an infrequent but potentially life-threatening complication of RT that, while not fully understood, is suspected to be partly an autoimmune reaction. Patient: We present the case of a 71-year-old female with a history of type 2 diabetes mellitus, hypothyroidism, interstitial cystitis, and osteoarthritis who presented with clinical stage T1N0M0 ER+/PR-/HER2-invasive ductal carcinoma of the lower outer quadrant of the left breast, for which she underwent left segmental mastectomy and sentinel lymph node biopsy followed by completion axillary lymph node dissection. Her final pathologic stage was T1N1M0. Result: The patient developed RRD and later RIOP following receipt of radiation and chemotherapy, which resolved with steroid administration. Conclusions: The rarity of both RRD and RIOP occurring in a patient, as in our case, suggests a shared pathophysiology behind these two complications. As both reactions involve some degree of inflammation and respond to corticosteroids, it seems likely that the etiologies of RRD and RIOP lie within the inflammatory pathway. However, further investigation should evaluate the frequency, duration, and triggering of concomitant RRD and RIOP.
