Psychological Treatment for Patients Receiving Radiation: Results of NRG Oncology/RTOG 0841.

PURPOSE: NRG/RTOG 0841 assessed the feasibility of a depression screening procedure in patients receiving radiation therapy (RT). As a secondary endpoint, availability and barriers to psychosocial care data were collected in hopes of providing recommendations for improved psychosocial care among patients receiving RT. METHODS AND MATERIALS: Patients starting RT were prospectively recruited and assessed with self-reported distress screening tools. Patients exceeding a validated cutoff and a sample of patients who screened negative received the Structured Clinical Interview for DSM-IV (SCID) mood disorder modules via telephone. During that SCID evaluation, patients completed a validated scale ranking interview on barriers to psychosocial care and interest in various psychosocial intervention modalities. RESULTS: A total of 463 patients from 35 community-based and 2 academic RT oncology sites were recruited. Of the 455 eligible, 75 (16%) exceeded screening cutoffs for depressive symptoms. From this group, 78 patients completed the SCID; most were female (76%), white (88%), and had breast cancer (55%). Overall, the most common barriers to treatment, regardless of insurance, were costs (58%), daily responsibilities (44%), and physical health symptoms (38%). Patients from RT facilities without mental health services were significantly more likely to report difficulty with physical health problems, specifically serious illness and walking, compared with those treated at RT facilities with services (P = .013 and P = .039, respectively). Overall, there was interest in obtaining psychosocial services with face-to-face counseling at the cancer center and printed educational materials as the most commonly preferred interventions. Patients with difficult barriers to psychosocial interventions were significantly less interested in support away from the cancer center (P = .016), telephone and Internet counseling (P = .0062 &P = .011), and Internet support (P = .0048). CONCLUSION: Radiation oncology patients are interested in obtaining psychosocial services but face barriers to access to mental health services including cost, debilitating symptoms, and time constraints that prevent adequate care.

Screening for depression in cancer patients receiving radiotherapy: Feasibility and identification of effective tools in the NRG Oncology RTOG 0841 trial.

BACKGROUND: Brief tools are needed to screen oncology outpatients for depressive symptoms. METHODS: Patients starting radiotherapy for the first diagnosis of any tumor completed distress screening tools, including the 9-item Patient Health Questionnaire (PHQ-9), the 2-item Patient Health Questionnaire (PHQ-2), the National Comprehensive Cancer Network Distress Thermometer (NCCN-DT), and the Hopkins Symptom Checklist (HSCL) (25-item version). Patients exceeding validated cutoff scores and a systematic sample of patients whose screening was negative completed the Structured Clinical Interview for DSM-IV (SCID) mood disorder modules via telephone. RESULTS: Four hundred sixty-three patients from 35 community-based radiation oncology sites and 2 academic radiation oncology sites were recruited. Sixty-six percent of the 455 eligible patients (n = 299) were women, and the eligible patients had breast (45%), gastrointestinal (11%), lung (10%), gynecologic (6%), or other cancers (27%). Seventy-five (16.5%) exceeded screening cutoffs for depressive symptoms. Forty-two of these patients completed the SCID. Another 37 patients whose screening was negative completed the SCID. Among the 79 patients completing the SCID, 8 (10.1%) met the criteria for major depression, 2 (2.5%) met the criteria for dysthymia, and 6 (7.6%) met the criteria for an adjustment disorder. The PHQ-2 demonstrated good psychometric properties for screening for mood disorders with a cutoff score of ≥3 (receiver operating characteristic area under the curve [AUC], 0.83) and was comparable to the PHQ-9 ( > 9; AUC = 0.85). The NCCN-DT did not detect depression (AUC = 0.59). CONCLUSIONS: The PHQ-2 demonstrated good psychometric properties for screening for mood disorders, which were equivalent to the PHQ-9 and superior to the NCCN-DT. These findings support using the PHQ-2 to identify patients in need of further assessment for depression, which has a low prevalence but is a clinically significant comorbidity. These findings could inform the implementation of distress screening accreditation standards. Cancer 2017;123:485-493. © 2016 American Cancer Society.

Ipsilateral breast tumor recurrence after breast conservation therapy: outcomes of salvage mastectomy vs. salvage breast-conserving surgery and prognostic factors for salvage breast preservation.

PURPOSE: To compare outcomes of salvage mastectomy (SM) and salvage breast-conserving surgery (SBCS) and study the feasibility of SBCS. METHODS AND MATERIALS: Of 2,038 patients treated with breast-conserving therapy at Yale-New Haven Hospital before 1999, 166 sustained an ipsilateral breast tumor recurrence (IBTR). Outcomes and prognostic factors of patients treated with SM or SBCS were compared. Patients were considered amenable to SBCS if the recurrence was localized on mammogram and physical examination, and had pathologic size < 3 cm, confined to the biopsy site, without skin or lymphovascular invasion, and with < or = 3 positive nodes. RESULTS: Of the 146 patients definitively managed at IBTR, surgery was SM (n = 116) or SBCS (n = 30). The median length of follow-up after IBTR was 13.8 years. The SM and SBCS cohorts had no significant differences, except at IBTR the SM cohort had a greater tumor size (p = 0.049). Of the SM cohort, 65.5% were considered appropriate for SBCS, and a localized relapse was predicted by estrogen-receptor positive, diploid, and detection of recurrence by mammogram. Multicentric disease correlated with BRCA1/2 mutation, estrogen-receptor negative, lymph node positive at relapse, and detection of recurrence by physical examination. Survival after IBTR was 64.5% at 10 years, with no significant difference between SM (65.7%) and SBCS (58.0%). Only 2 patients in the SBCS cohort subsequently had a second IBTR, and were salvaged with mastectomy. CONCLUSIONS: While mastectomy is considered the standard surgical salvage of IBTR, SBCS is feasible and prognostic factors are related to favorable tumor biology and early detection. Patients with BRCA1/2 germline mutations may be less appropriate for SBCS, as multicentric disease was more prevalent. Patients who underwent SBCS had comparable outcomes as those who underwent SM, but remain at continued risk for IBTR. A prospective trial evaluating repeat lumpectomy and partial breast reirradiation is discussed.

Dose-intensive thoracic radiation therapy for patients at high risk with early-stage non-small-cell lung cancer.

Recent studies suggest that radiation therapy (RT) dose escalation in early-stage non-small-cell lung cancer (NSCLC) is feasible when 3-dimensional therapy is used. However, the accompanying prolongation of the treatment course when standard fractionation is used could be suboptimal from a practical and biologic standpoint. We report results of a compressed course of RT for patients with pathologically documented clinical stage 1 NSCLC who were unsuitable for curative surgery because of pulmonary dysfunction or other medical comorbidities. Thirty-one lesions were treated with dose-intensive RT (eg, fraction>or=2.25 Gy and nominal total dose>or=60 Gy) and have been followed up for >or=6 months from the completion of treatment. All patients completed therapy without interruption. Three patients developed grade 3 pulmonary toxicity 1-3 months after therapy. The overall tumor response rate was 88% (35% complete response and 53% partial response), whereas in-field tumor progression was documented for 5 of 31 lesions. Actuarial median survival was 38 months and 3-year overall survival was 60%, and most deaths were secondary to intercurrent disease. Moderately accelerated single daily fractionated RT is feasible for high-risk patients with early-stage NSCLC and merits further investigation.

Gamma knife surgery for trigeminal neuralgia: improved initial response with two isocenters and increasing dose.

OBJECT: The authors sought to evaluate the initial response of trigeminal neuralgia (TN) to gamma knife surgery (GKS) based on the number of shots delivered and radiation dose. METHODS: Between September 1998 and September 2003, some 63 patients with TN refractory to medical or surgical management underwent GKS at Upstate Medical University. Ten patients had multiple sclerosis and 25 patients had undergone prior invasive treatment. Gamma knife surgery was delivered to the trigeminal nerve root entry zone in one shot in 27 patients or two shots in 36 patients. The radiation dose was escalated to less than or equal to 80 Gy in 20 patients, 85 Gy in 21 patients, and greater than or equal to 90 Gy in 22 patients. Pain before and after GKS was assessed using the Barrow Neurological Institute Pain Scale and the improvement score was analyzed as a function of dose grouping and number of shots. Sixty patients were available for evaluation, with an initial overall and complete response rate of 90% and 27%, respectively. There was a greater improvement score for patients who were treated with two shots compared with one shot, mean 2.83 compared with 1.72 (p < 0.001). There was an increased improvement in score at each dose escalation level: less than or equal to 80 Gy (p = 0.017), 85 Gy (p < 0.001), and greater than or equal to 90 Gy (p < 0.001). Linear regression analysis also indicated that there was a greater response with an increased dose (p = 0.021). Patients treated with two shots were more likely to receive a higher dose (p < 0.001). There were no severe complications. Five patients developed mild facial numbness. CONCLUSIONS: Gamma knife surgery is an effective therapy for TN. Initial response rates appear to correlate with the number of shots and dose.

Conservative management of breast cancer in BRCA1/2 mutation carriers.

Breast-conserving therapy is widely embraced for the majority of women with early-stage breast cancer, but its appropriateness in patients with germline mutations of BRCA1 and BRCA2 remains controversial. These breast cancer susceptibility genes are associated with a progressive risk of second cancers, although the prognosis of BRCA-associated breast cancer is similar to that in patients with sporadic disease. The BRCA1/2 genes are involved in the cellular response to DNA damage, but their molecular functions are not fully understood. Preclinical evidence of radiation sensitivity has led to concerns regarding radiation-induced complications in patients with BRCA1/2 mutations. The published literature on conservative management of patients with BRCA1/2 mutations is reviewed in this article. Several studies report no adverse sequelae and recurrence rates and overall survival comparable to those in sporadic disease controls. With longer follow-up, the literature suggests an increase in late second primary breast cancers, highlighting the need for preventive strategies. The potential role of tamoxifen and oophorectomy in modifying the rate of second events is discussed.

Radiotherapy for the clinically negative neck in supraglottic laryngeal cancer.

PURPOSE: The supraglottic larynx has rich lymphatic drainage, resulting in a high incidence of occult cervical metastases, and the optimal treatment of the clinically uninvolved neck in supraglottic laryngeal cancer remains controversial. Selected retrospective series report a greater than 20% regional failure after treatment by radiotherapy alone, and some investigators recommend routine prophylactic neck dissection. We report on our series of patients who received radiotherapy as sole treatment to the clinically negative neck, either to the bilateral neck for N0 disease or to the contralateral neck for ipsilateral lymphatic involvement. PATIENTS AND METHODS: Between 1971 and 1998, 150 patients with supraglottic laryngeal cancer received radiotherapy alone to the clinically negative neck. Fifty-two patients had ipsilateral lymph node metastases (N1 = 16, N2a = 12, N2b = 20, N3 = 4), and 98 patients had no clinical nodal involvement. The primary site (T1/T2 = 74, T3/T4 = 76) was treated with radiotherapy (N = 91) or laryngectomy plus radiotherapy (N = 59). Neck dissection was performed on the involved neck in 36/52 node-positive patients for either multiple involved nodes (N = 20) or size > 3 cm (N = 16). Radiotherapy was delivered in standard fractionation and field arrangement. The median dose to the clinically negative neck was 5000 cGy (range: 4860-6000 cGy). RESULTS: With a median follow-up of 48 months, the clinically negative neck was the first site of failure in 3.3% of patients. The contralateral neck remained disease free in all patients. Five failures occurred in the N0 neck, and the median time to recurrence was 12 months (range: 5-30 months). Salvage therapy was neck dissection for the N0 neck failures. The 5-year locoregional control, disease-specific survival, and overall survival were 69%, 74%, and 61%, respectively. DISCUSSION: Our data support the use of radiotherapy as a prophylactic treatment for the clinically negative neck. Tumor control in the clinically uninvolved cervical lymphatics is comparable to that in surgical series, suggesting that routine neck dissection may not be necessary. Prospective trials are necessary to further define the role of radiotherapy in this patient population.

Radiotherapy for moderate-to-severe Graves' ophthalmopathy: improved outcomes with early treatment.

PURPOSE: The purpose of this review is to quantify the response to radiotherapy delivered early in the active inflammatory phase of moderate-to-severe Graves' ophthalmopathy. MATERIALS AND METHODS: A retrospective review of radiotherapy delivered early in the active phase of Graves' ophthalmopathy was performed. All 47 cases had moderate-to-severe ophthalmopathy, and 30 cases had optic neuropathy. Variables examined included exophthalmos, color vision, and resistance to retropulsion. Statistical analyses comparing these variables at presentation and at 3 and 6 months after radiotherapy were performed. Subset analyses comparing responses of patients with symptoms lasting longer or less than 6 months were also performed. RESULTS: At 6 months after radiotherapy, there was improvement in exophthalmos in 74.5% of cases and improvement in retropulsion in 83.0%, and all cases of previous color deficiency improved. The mean improvement in exophthalmos was 1.38 mm, color vision was two plates, and retropulsion was 1 grade. On subset analyses, there was a trend toward greater improvement in patients treated earlier in the course of their symptoms. CONCLUSIONS: Radiotherapy may play an important role in the treatment of Graves' ophthalmopathy, especially for patients with optic neuropathy. Early intervention (symptoms < 6 months) with radiotherapy may be the optimal timing for this treatment.

Successful treatment of spindle cell sarcoma of the sella turcica. Case report.

A primary spindle cell sarcoma of the sella turcica in a patient without a history of radiation treatment is a very rare occurrence. Only one other case has been reported to date, with local recurrence 7 months after the patient underwent subtotal resection and stereotactic radiosurgery of the tumor. The authors present a case of spindle cell sarcoma of the sella turcica successfully treated by surgery, external-beam radiotherapy, and gamma knife radiosurgery. After 24 months of follow up, the patient continues to show no evidence of disease.
