Gross Tumor and Intracranial Control Benefits with Fractionated Radiotherapy Compared with Stereotactic Radiosurgery for Patients with WHO Grade 2 Meningioma.

OBJECTIVE: Surgical resection is the mainstay of treatment for WHO grade 2 meningioma. Fractionated radiation therapy (RT) is frequently used after surgery, though many centers utilize stereotactic radiosurgery (SRS) for recurrence or progression. Herein, we report disease control outcomes from an institutional cohort with adjuvant fractionated RT versus salvage SRS. METHODS: We identified 32 patients from an institutional database with WHO grade 2 meningioma and residual/recurrent tumor treated with either SRS or fractionated RT. Patients were treated between 2007 and 2021 and had at least 1 year of follow-up. Kaplan-Meier estimators were used to determine gross tumor control (GTC) and intracranial control (IC). Univariate Cox proportional hazards models using biologically effective dose (BED) as a continuous parameter were used to assess for dose responses. RESULTS: With a median follow-up of 5.5 years, 13 patients (41%) received SRS to a recurrent or progressive nodule, 2 (6%) fractionated RT to a recurrent or progressive nodule, and 17 (53%) adjuvant fractionated RT following subtotal resection. Five-year GTC was higher with fractionated RT versus SRS (82% vs. 38%, P = 0.03). Five-year IC was also better with fractionated RT versus SRS (82% vs. 11%, P < 0.001). On univariate analysis, increasing BED10 was significantly associated with better GTC (P = 0.039); increasing BED3 was not (P = 0.82). CONCLUSIONS: In this patient cohort, GTC and IC were significantly higher in patients treated with adjuvant fractionated RT compared with salvage SRS. Increasing BED10 was associated with better GTC. Fractionated RT may provide a better therapeutic ratio than SRS for grade 2 meningiomas.

The Role of Axillary Lymph Node Dissection versus Sentinel Lymph Node Dissection in Breast Cancer Patients with Clinical N2b-N3c Disease Who Receive Adjuvant Radiotherapy.

BACKGROUND: For breast cancer with advanced regional lymph node involvement, axillary lymph node dissection (ALND) remains the standard of care for staging and treating the axilla despite the presence of undissected lymph nodes. The benefit of ALND in this setting is unknown. OBJECTIVES: We sought to describe national patterns of care of axillary surgery and its association with overall survival (OS) among women with cN2b-N3c breast cancer who receive adjuvant radiotherapy. PATIENTS AND METHODS: We identified female patients with cN2b-N3c breast cancer from 2012 to 2017 from the National Cancer Database. Clinical and demographic information were analyzed using Wilcoxon rank sum and χ2 tests. Predictors of receipt of ALND and predictors of death were identified with multivariable logistic regression modeling. Inverse probability of treatment weighting was implemented to adjust for differences in treatment cohorts. The Kaplan-Meier method was used to evaluate OS. RESULTS: We identified 7167 patients. Of these, 922 (13%) received SLNB and 6254 (87%) received ALND; 7% were cN2b, 19% cN3a, 24% cN3b, 19% cN3c, and 31% cN3, not otherwise specified. Predictors of receipt of ALND were age 50-69 years [odds ratio (OR) 1.3, p < 0.01], cN3a (OR 7.6, p < 0.01), cN3b (OR 2.8, p < 0.01), and cN3c (OR 4.2, p < 0.01). Predictors of death included cN3c (OR 1.9, p < 0.01), age 70-90 years (OR 1.5, p = 0.01), and positive surgical margins (OR 1.5, p < 0.01). After cohort balancing, ALND was not associated with improved OS when compared with SLNB (HR 0.99, p = 0.91). CONCLUSIONS: ALND in patients with advanced nodal disease was not associated with improved survival compared with SLNB for women who receive adjuvant radiotherapy.

Differentiation of survival outcomes by anatomic involvement and histology with the revised 2023 International Federation of Gynecology and Obstetrics staging system for endometrial cancer.

OBJECTIVES: The International Federation of Gynecology and Obstetrics (FIGO) staging system for endometrial cancer underwent revision in 2023, incorporating histology, lymphovascular space invasion, and molecular classification. Herein, we compare overall survival (OS) outcomes by anatomic and histologic involvement for patients staged by the 2009 system versus 2023 system. METHODS: The National Cancer Database (NCDB) was queried for patients with newly-diagnosed uterine adenocarcinoma from 2004 to 2015, with follow-up data extending through 2020. Stage was determined by both the 2009 and 2023 FIGO staging systems. Kaplan-Meier estimators and Cox proportional hazards models were used for survival analysis. RESULTS: A total of 134,677 patients were analyzed. Per 2023 classification, patients with stage I disease decreased from 96,161 to 70,101 (-27.1%, p < 0.01), while stage II disease increased from 9295 to 36,294 (+390.5%, p < 0.01). Greatest OS change was observed for 2023 stage IA3 patients (low-risk, synchronous endometrial and ovarian tumors with a clonal relationship), whose 10-year OS was 73.4%, compared to 52.6% for 2009 stage IIIA disease. Ten-year OS for 2023 stage IIIB2 (pelvic peritoneal involvement), previously 2009 stage IVB, was 49.4%, compared to 18.7% for 2009 stage IVB patients. Akaike information criterion, Bayesian information criterion, and Harrel's concordance index were used to evaluate OS prognostication of each staging system across all stages, with likelihood ratio favoring the 2023 system (p = 0.020). CONCLUSIONS: With FIGO's 2023 endometrial cancer anatomic and histologic staging system, stage migration is greatest in early-stage disease. New staging groups may offer more precise prognostication. These changes may affect future management.

Patterns of failure after radiosurgery for WHO grade 1 or imaging defined meningiomas: Long-term outcomes and implications for management.

BACKGROUND: We analyzed long-term control and patterns of failure in patients with World Health Organization Grade 1 meningiomas treated with definitive or postoperative stereotactic radiosurgery at the authors' affiliated institution. METHODS: 96 patients were treated between 2004 and 2019 with definitive (n = 57) or postoperative (n = 39) stereotactic radiosurgery. Of the postoperative patients, 17 were treated adjuvantly following subtotal resection and 22 were treated as salvage at time of progression. Patients were treated to the gross tumor alone without margin or coverage of the dural tail to a median dose of 15 Gy. Median follow up was 7.4 years (inter-quartile range 4.8-11.3). Local control, marginal control, regional control, and progression-free survival were analyzed. RESULTS: Local control at 5 and 10 years was 97 % and 95 %. PFS at 5 and 10 years was 94 % and 90 % with no failures reported after 6 years. Definitive and postoperative local control were similar at 5 (95 % [82-99 %] vs. 100 %) and 10 years (92 % [82-99 %] vs. 100 %). Patients treated with postoperative SRS did not have an increased marginal failure rate (p = 0.83) and only 2/39 (5 %) experienced recurrence elsewhere in the cavity. CONCLUSIONS: Stereotactic radiosurgery targeting the gross tumor alone provides excellent local control and progression free survival in patients treated definitively and postoperatively. As in the definitive setting, patients treated postoperatively can be treated to gross tumor alone without need for additional margin or dural tail coverage.

Multi-Institutional Analysis of Cancer Patient Exposure, Perceptions, and Trust in Information Sources Regarding Complementary and Alternative Medicine.

PURPOSE: Complementary and alternative medicine (CAM) use during cancer treatment is controversial. We aim to evaluate contemporary CAM use, patient perceptions and attitudes, and trust in various sources of information regarding CAM. METHODS: A multi-institutional questionnaire was distributed to patients receiving cancer treatment. Collected information included respondents' clinical and demographic characteristics, rates of CAM exposure/use, information sources regarding CAM, and trust in each information source. Comparisons between CAM users and nonusers were performed with chi-squared tests and one-way analysis of variance. Multivariable logistic regression models for trust in physician and nonphysician sources of information regarding CAM were evaluated. RESULTS: Among 749 respondents, the most common goals of CAM use were management of symptoms (42.2%) and treatment of cancer (30.4%). Most CAM users learned of CAM from nonphysician sources. Of CAM users, 27% reported not discussing CAM with their treating oncologists. Overall trust in physicians was high in both CAM users and nonusers. The only predictor of trust in physician sources of information was income >$100,000 in US dollars per year. Likelihood of trust in nonphysician sources of information was higher in females and lower in those with graduate degrees. CONCLUSION: A large proportion of patients with cancer are using CAM, some with the goal of treating their cancer. Although patients are primarily exposed to CAM through nonphysician sources of information, trust in physicians remains high. More research is needed to improve patient-clinician communication regarding CAM use.

Trends in use of radiation therapy, chemotherapy, and combination chemoradiotherapy in advanced uterine cancer before, during, and after GOG 258.

OBJECTIVE: To explore the use of Gynecologic Oncology Group 258 (GOG 258) study regimens before, during, and after the study. METHODS: Patients aged 18 years or older with endometrial cancer between 2004-2019 were identified in the National Cancer Database. Inclusion criteria were stage III or IVA of any histology and stage I-IVA clear cell or serous histologies with positive washings that received adjuvant therapy. Adjuvant therapy use was examined in the pre-GOG 258 era (before 2009), during GOG 258 enrollment and maturation (2010-2017), and after results presentation in 2017 (2018-2019). Two-sided Cochran-Armitage tests, Wilcoxen rank sum tests, and χ2 tests were used for continuous and categorical variables. Multi-variable logistic regression assessed factors associated with the receipt of chemoradiotherapy compared with chemotherapy only or radiation therapy only. RESULTS: From 2004 to 2019, 41 408 high-risk endometrial cancer patients received adjuvant therapy (12% radiation therapy, 38% chemotherapy, 50% chemoradiotherapy). Chemoradiotherapy increased over the GOG 258 study period (40% before study opening, 54% during enrollment, and 59% after results). Serous (OR 0.6, 95% CI 0.6 to 0.7) and clear cell histology (0.7, 0.6 to 0.8), higher grade (0.8, 0.7 to 0.9), and lymph node positivity (0.8, 0.7 to 0.9) were negatively associated with receipt of chemoradiotherapy compared with single-modality treatment. Non-Hispanic Black ethnicity (0.8, 0.8 to 0.9) and residing ≥50 miles from the treatment facility (0.8, 0.7 to 0.9) were also negatively associated with chemoradiotherapy. Private insurance (1.2, 1.0 to 1.4) and treatment at community hospitals (1.2, 1.2 to 1.3) were positively associated with chemoradiotherapy. CONCLUSION: Despite the lack of benefit in the GOG 258 experimental arm, chemoradiotherapy use increased during study enrollment and after results publication.

Patterns of Care and Utilization Disparities in Proton Radiation Therapy for Pediatric Central Nervous System Malignancies.

Purpose: Proton radiation therapy (PR) is well established in the treatment of pediatric malignancies in the central nervous system (CNS) with dosimetric advantages that reduce late radiation therapy (RT) effects. In this analysis, we sought to evaluate the utilization of PR in children with primary CNS malignancies and characterize the clinical and sociodemographic factors predictive of receipt of PR. Methods and Materials: The National Cancer Database was queried to identify all pediatric patients with primary CNS malignancies treated with curative intent RT from 2004 to 2017. Clinical characteristics and demographics were analyzed using standard t and χ2 testing. Predictors of PR receipt were identified with univariable and multivariable logistic regression. Results: We identified 9126 patients ≤18 years of age treated with RT between 2004 and 2017, of which 1045 (11.5%) received PR. PR usage continued to increase significantly, from <1% in 2004 to 28% in 2017. The proportion of white and Asian patients receiving PR for nonhigh-grade glioma and nonmeningioma CNS malignancies during the study period rose from <1% for both to 35% and 44%, respectively, and in black patients the proportion rose from <1% to 26%. Multivariable predictors of receipt of PR include year of diagnosis, age <6 years, income level, distance from PR facility, and histology; multivariable predictors of receipt of photon RT include black race, rural residence, and Medicaid insurance. These factors remained significant when isolating the most recent 5 years of data. Conclusions: Proton radiation therapy usage for CNS malignancies increased significantly during the study period. Despite the potential clinical advantages of PR for pediatric primary CNS malignancies, there are notable socioeconomic, geographic, and racial disparities in the receipt of PR that persisted despite the increased availability and accessibility. Further study is warranted to identify how to address the disparities and better support these patients.

Incidence and extent of disease progression on MRI between surgery and initiation of radiotherapy in glioblastoma patients.

Background: A post-operative MRI (MRIpost-op) performed within 72 h is routinely used for radiation treatment planning in glioblastoma (GBM) patients, with radiotherapy starting about 4-6 weeks after surgery. Some patients undergo an additional pre-radiotherapy MRI (MRIpre-RT) about 2-6 weeks after surgery. We sought to analyze the incidence of rapid early progression (REP) between surgery and initiation of radiotherapy seen on MRIpre-RT and the impact on radiation target volumes. Methods: Patients with GBM diagnosed between 2018 and 2020 who had an MRIpost-op and MRIpre-RT were retrospectively identified. Criteria for REP was based on Modified RANO criteria. Radiation target volumes were created and compared using the MRIpost-op and MRIpre-RT. Results: Fifty patients met inclusion criteria. The median time between MRIpost-op and MRIpre-RT was 26 days. Indications for MRIpre-RT included clinical trial enrollment in 41/50 (82%), new symptoms in 5/50 (10%), and unspecified in 4/50 (8%). REP was identified in 35/50 (70%) of patients; 9/35 (26%) had disease progression outside of the MRIpost-op-based high dose treatment volumes. Treatment planning with MRIpost-op yielded a median undertreatment of 27.1% of enhancing disease and 11.2% of surrounding subclinical disease seen on MRIpre-RT. Patients without REP had a 38% median volume reduction of uninvolved brain if target volumes were planned with MRIpre-RT. Conclusion: Given the incidence of REP and its impact on treatment volumes, we recommend using MRIpre-RT for radiation treatment planning to improve coverage of gross and subclinical disease, allow for early identification of REP, and decrease radiation treatment volumes in patients without REP.

Racial and Ethnic Health Disparities in Delay to Initiation of Intensity-Modulated Radiotherapy.

PURPOSE: Delays in initiation of radiotherapy may contribute to inferior oncologic outcomes that are more commonly observed in minoritized populations in the United States. We aimed to examine inequities associated with delayed initiation of intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS: The National Cancer Database was queried to identify the 10 cancer sites most commonly treated with IMRT. Interval to initiation of treatment (IIT) was broken into quartiles for each disease site, with the 4th quartile classified as delayed. Multivariable logistic regression for delayed IIT was performed for each disease site using clinical and demographic covariates. Differences in magnitude of delay between subsets of patients stratified by race and insurance status were evaluated using two-sample t-tests. RESULTS: Among patients (n = 350,425) treated with IMRT between 2004 and 2017, non-Hispanic Black (NHB), Hispanic, and Asian patients were significantly more likely to have delayed IIT with IMRT for nearly all disease sites compared with non-Hispanic White (NHW) patients. NHB, Hispanic, and Asian patients had significantly longer median IIT than NHW patients (NHB 87 days, P < .01; Hispanic 76 days, P < .01; Asian 74 days, P < .01; and NHW 67 days). NHW, Hispanic, and Asian patients with private insurance had shorter median IIT than those with Medicare (P < .01); however, NHB patients with private insurance had longer IIT than those with Medicare (P < .01). CONCLUSION: Delays in initiation of IMRT in NHB, Hispanic, and Asian patients may contribute to the known differences in cancer outcomes and warrant further investigation, particularly to further clarify the role of different insurance policies in delays in advanced modality radiotherapy.

Patterns of care and outcomes of early stage I-II Hodgkin lymphoma treated with or without radiation therapy.

Omission of radiotherapy in the upfront management of early-stage classic Hodgkin lymphoma (cHL) has become more common with time. We report patterns of care and outcomes of stage I-II cHL treated with chemotherapy (CT) only versus CT and radiotherapy (combined modality therapy, CMT). From the National Cancer Database, we identified 28,327 early-stage cHL patients treated with CT (n = 15,798) or CMT (n = 12,529) from 2004 to 2018. CMT utilization declined over the period from 58% to 34%. With median follow-up of 6.2 years, the 5- and 10-year overall survival for CT versus CMT was 93.3% versus 96.9% (p < 0.001) and 88.7% versus 93.5% (p < 0.001), respectively. On multivariable analysis, uninsured (OR 0.75, p < 0.001) and Black patients (OR 0.86, p = 0.02) were less likely to receive CMT, and treatment with CT was predictive of death (OR 2.0, p < 0.001). This report highlights real-world outcomes in early-stage cHL, with worse survival with CT and notable disparities in CMT utilization.

Radiation Therapy in Conjunction With Surgical Stabilization of Impending or Pathologic Fractures Secondary to Metastasis: Is There a Difference Between Single and Multifraction Regimens?

PURPOSE: Patients who undergo surgical stabilization for impending or pathologic fractures secondary to metastasis are often treated with radiation therapy to the involved site. We sought to retrospectively analyze outcomes from single versus multifraction regimens of radiation therapy in this setting. METHODS AND MATERIALS: From our institutional radiation database, we identified 87 patients between 2004 and 2016 who had an impending or pathologic fracture from metastatic disease and who underwent surgical fixation in conjunction with either neoadjuvant (within 5 weeks before surgery) or adjuvant (within 10 weeks after surgery) radiation therapy, representing 99 total treatment sites. Patients were included on the basis of intention to treat with bimodality therapy. Baseline patient characteristics were compared using 2-sided t tests and Fisher's exact tests. Cumulative incidence of local failure, reirradiation, and reoperation were calculated using the Fine-Gray method for competing risks. Freedom from complication was calculated using the Kaplan-Meier method. RESULTS: Baseline characteristics between the single (n = 52) and multifraction (n = 47) cohorts were similar with the exception of higher rates of synchronous bony metastasis (83% vs 60%, P = .01) and female patients (71% vs 43%, P = .004) in the single fraction cohort. There was no significant difference in overall survival between treatment groups. After a median follow-up of 13 months, there was no significant difference in the single and multifraction cohorts, respectively, in the 1-year cumulative incidence rates of local failure (4% vs 7%, P = .58), reirradiation (5% vs 4%, P = .95), reoperation (4% vs 0%, P = .30), or 1-year freedom from complication (90% vs 95%, P = .40). CONCLUSIONS: This is the first study comparing outcomes between single and multifraction radiation therapy in conjunction with surgical stabilization of an impending or pathologic fracture. We found no difference in outcomes between single and multifraction regimens in this setting. Given these findings, single fraction perioperative radiation therapy may be a viable treatment option in appropriately selected patients pending prospective validation of these findings.

Comparing adjuvant radiation to adjuvant chemoradiation in postsurgical p16+ oropharyngeal carcinoma patients with extranodal extension or positive margins.

BACKGROUND: Adjuvant guidelines in surgically resected p16+ oropharyngeal carcinoma (OPC) with positive surgical margins (PSM) or extranodal extension (ENE) are based on randomized controlled trials predating p16 status. It remains unclear if adjuvant chemotherapy is necessary in p16+ patients with these features. METHODS: The National Cancer Database was used to identify cases of nonmetastatic p16+ OPC diagnosed from 2010 to 2017. Patients treated with surgical resection followed by adjuvant radiation (aRT) or adjuvant chemoradiation (aCRT) were eligible for analysis. RESULTS: A total of 14 071 patients were eligible for analysis. Overall survival (OS) was not statistically different between aRT and aCRT in patients with PSM (hazard ratio (HR) 0.84, 95% confidence interval (CI) 0.56-1.28), ENE (HR 0.93, 95% CI 0.69-1.27) or both (HR 0.73, 95% CI 0.41-1.31). CONCLUSIONS: In patients with p16+ OPC with ENE, PSM, or both, adding chemotherapy to aRT was not associated with improved OS.

Patterns of Care and Treatment Outcomes in Locoregional Squamous Cell Carcinoma of the Prostate.

Primary squamous cell carcinoma is a rare, aggressive disease with historically poor outcomes and no established treatment guidelines. Case reports are limited but describe multiple treatment approaches. Seeking to identify practice patterns and treatment outcomes, we used the US National Cancer Data Base to identify 66 males with locoregional primary squamous cell carcinoma of the prostate treated with surgery, chemotherapy, and/or radiotherapy between 2004 and 2015. Patients were stratified into treatment groups consisting of local therapy alone (n = 40; 61%), local therapy and chemotherapy (n = 13; 20%), chemotherapy alone (n = 7; 11%), and observation (n = 6; 9%). Patients with clinical stage T3-T4 disease were significantly more likely to receive combined chemotherapy and local therapy on multivariable analysis. Median survival was 20 mo for patients treated with local therapy alone, 37 mo with local therapy and chemotherapy, and 11 mo with chemotherapy alone. Overall survival was not significantly different between treatment groups. Despite limitations in sample size, these data suggest that addition of chemotherapy to local therapy is a reasonable treatment approach for select patients. PATIENT SUMMARY: Squamous cell carcinoma of the prostate is an extremely rare disease. Our review of patterns of care using data from the National Cancer Data Base shows inconsistent use of combined local and systemic therapy. The small sample size for this rare disease limits any conclusions regarding survival differences, but the data suggest that a combination approach using chemotherapy in addition to surgery or radiation is a reasonable treatment option for disease confined to the prostate.

Temporal Trends and Predictors in Diagnosing Pathologic Node-Positive Prostate Cancer in Clinically Node-Negative Patients.

INTRODUCTION: Managing pathologically node positive (pN+) prostate cancer (PCa) is controversial. We describe temporal patterns and predictors of pN+ PCa in men with initially surgically managed clinically node negative (cN-) PCa. MATERIALS AND METHODS: This observational retrospective analysis of nonmetastatic, cN- PCa uses the National Cancer Database. Multivariable logistic regression was used to identify covariates associated with pN+ disease. Cox proportional hazards modeling and Kaplan-Meier analysis were used to evaluate survival patients undergoing radical prostatectomy with or without pelvic lymph node dissection (PLND). RESULTS: The rates of radical prostatectomy in men with grade group (GG) 4 and GG5 increased from 47.6% to 53.1% and from 42.5% to 49.5%, respectively. The annual rate increased from 2.02% in 2010 to 5.12% in 2017 (P < .001). The annual rates of PLND increased from 54.3% to 71.7%. The most significant predictor of pN+ PCa was ISUP GG4 (odds ratio [OR] 12.5, P< .001) and GG 5 (OR 26.2, P < .001). Rates of pN+ identification increased from 5.5% to 9.4% in men with GG4 and from 13.4% to 19.5% in men with GG5 (P< .001). In GG4 and GG5, patients undergoing PLND had superior survival to those managed without PLND (P < .01). CONCLUSION: Among patients with cN- PCa, the diagnosis of pN+ PCa has become more common over time. GG4 and GG5 are the strongest independent predictors of pN+ disease. Because incidental pN+ results in upstaging these data are useful for informing discussions before radical prostatectomy.

A Rare Cause of Cough: Tracheobronchial Myxoid Spindle Cell Lipoma.

BACKGROUND: Endobronchial lipomas are a particularly rare form of benign lung neoplasms, with an incidence of 0.1-0.4%. They are often clinically silent, though present with nonspecific symptoms that can result in extensive workup or significant delay prior to diagnosis, as presented in this case. Case Presentation. A 61-year-old male presented with chronic productive cough and occasional dyspnea and a 10-year history of clinically diagnosis of intermittent, exercise-induced asthma, nonresponsive to bronchodilators, and with normal pulmonary function tests. A chest ray showed a band-like opacity in the right middle lobe of the lung and a CT of the chest showed right lung atelectasis with a soft tissue mass in the right main bronchus. The patient underwent bronchoscopy with biopsy, which demonstrated an endobronchial myxoid spindle cell lipoma. The lesion was subsequently removed by a bronchoscopic snare. The patient's asthmatic-like symptomatology resolved after the mass was excised. CONCLUSION: Though rare, endobronchial lipomas characteristically present with nonspecific signs and symptoms and thus can be easily mistaken for other medical conditions, delaying diagnosis and prolonging symptoms.

Long-term outcomes of patients with unfavorable stage I-II classic Hodgkin lymphoma treated with Stanford V chemotherapy and limited field irradiation.

Management of stage I-II unfavorable risk Hodgkin lymphoma (HL) strives to reduce toxicity while maintaining tumor control. Compared to ABVD or BEACOPP, Stanford V chemotherapy contains less doxorubicin and bleomycin. We report long-term outcomes of patients with stage I-II classic HL with European risk factors treated with Stanford V combined modality therapy (CMT). From our institutional cancer registry, we identified 168 patients with ≥1 European risk factor treated with 8-12 weeks of Stanford V CMT and consolidative radiotherapy between 1990 and 2016. Outcomes were analyzed after classification by EORTC and GHSG unfavorable criteria. With median follow-up of 8.4 years, 10-year overall survival and progression-free survival for the entire cohort were 95% and 88%, respectively. Thirteen of 18 relapses were salvaged successfully. There were no cases of MDS or AML after primary therapy. Long-term outcomes of stage I-II unfavorable risk HL treated with Stanford V CMT are comparable to ABVD or BEACOPP regimens.
