RESUMO
BACKGROUND: Minimally invasive radical trachelectomy has emerged as an alternative to open radical hysterectomy for patients with early-stage cervical cancer desiring future fertility. Recent data suggest worse oncologic outcomes after minimally invasive radical hysterectomy than after open radical hysterectomy in stage I cervical cancer. OBJECTIVE: We aimed to compare 4.5-year disease-free survival after open vs minimally invasive radical trachelectomy. STUDY DESIGN: This was a collaborative, international retrospective study (International Radical Trachelectomy Assessment Study) of patients treated during 2005-2017 at 18 centers in 12 countries. Eligible patients had squamous carcinoma, adenocarcinoma, or adenosquamous carcinoma; had a preoperative tumor size of ≤2 cm; and underwent open or minimally invasive (robotic or laparoscopic) radical trachelectomy with nodal assessment (pelvic lymphadenectomy and/or sentinel lymph node biopsy). The exclusion criteria included neoadjuvant chemotherapy or preoperative pelvic radiotherapy, previous lymphadenectomy or pelvic retroperitoneal surgery, pregnancy, stage IA1 disease with lymphovascular space invasion, aborted trachelectomy (conversion to radical hysterectomy), or vaginal approach. Surgical approach, indication, and adjuvant therapy regimen were at the discretion of the treating institution. A total of 715 patients were entered into the study database. However, 69 patients were excluded, leaving 646 in the analysis. Endpoints were the 4.5-year disease-free survival rate (primary), 4.5-year overall survival rate (secondary), and recurrence rate (secondary). Kaplan-Meier methods were used to estimate disease-free survival and overall survival. A post hoc weighted analysis was performed, comparing the recurrence rates between surgical approaches, with open surgery being considered as standard and minimally invasive surgery as experimental. RESULTS: Of 646 patients, 358 underwent open surgery, and 288 underwent minimally invasive surgery. The median (range) patient age was 32 (20-42) years for open surgery vs 31 (18-45) years for minimally invasive surgery (P=.11). Median (range) pathologic tumor size was 15 (0-31) mm for open surgery and 12 (0.8-40) mm for minimally invasive surgery (P=.33). The rates of pelvic nodal involvement were 5.3% (19 of 358 patients) for open surgery and 4.9% (14 of 288 patients) for minimally invasive surgery (P=.81). Median (range) follow-up time was 5.5 (0.20-16.70) years for open surgery and 3.1 years (0.02-11.10) years for minimally invasive surgery (P<.001). At 4.5 years, 17 of 358 patients (4.7%) with open surgery and 18 of 288 patients (6.2%) with minimally invasive surgery had recurrence (P=.40). The 4.5-year disease-free survival rates were 94.3% (95% confidence interval, 91.6-97.0) for open surgery and 91.5% (95% confidence interval, 87.6-95.6) for minimally invasive surgery (log-rank P=.37). Post hoc propensity score analysis of recurrence risk showed no difference between surgical approaches (P=.42). At 4.5 years, there were 6 disease-related deaths (open surgery, 3; minimally invasive surgery, 3) (log-rank P=.49). The 4.5-year overall survival rates were 99.2% (95% confidence interval, 97.6-99.7) for open surgery and 99.0% (95% confidence interval, 79.0-99.8) for minimally invasive surgery. CONCLUSION: The 4.5-year disease-free survival rates did not differ between open radical trachelectomy and minimally invasive radical trachelectomy. However, recurrence rates in each group were low. Ongoing prospective studies of conservative management of early-stage cervical cancer may help guide future management.

BACKGROUND: Value in healthcare is reflected by patient-centered outcomes of care per health dollar expended. Although liposomal bupivacaine is more expensive, it has been shown to provide prolonged analgesia (up to 72 hours). OBJECTIVE: This study aimed to evaluate whether the addition of liposomal bupivacaine to standard bupivacaine could decrease opioid intake and improve pain control after laparotomy for gynecologic surgery compared with standard bupivacaine alone in an enhanced recovery after surgery pathway. STUDY DESIGN: A prospective randomized controlled single-blinded trial of wound infiltration with liposomal bupivacaine plus 0.25% bupivacaine (study arm) vs 0.25% bupivacaine (control arm) was performed at a National Cancer Institute-designated tertiary referral cancer center. Participants were patients aged ≥18 years undergoing exploratory laparotomy for a gynecologic indication. All patients were treated on an enhanced recovery pathway including local wound infiltration before closure. In this study, 266 mg of liposomal bupivacaine (free base; equal to 300 mg bupivacaine HCL)+150 mg of bupivacaine mixed in the same syringe was used in the study arm, and 150 mg of bupivacaine was used in the control arm. The primary outcome was the proportion of patients who were opioid-free within 48 hours after surgery. Secondary outcomes included number of opioid-free days from postoperative day 0 to postoperative day 3, days to first opioid administration, morphine equivalent daily dose, and patient-reported outcomes collected with the MD Anderson Symptom Inventory. The MD Anderson Symptom Inventory was administered as a preoperative baseline, daily while hospitalized, and at least weekly for 8 weeks after discharge. All outcomes were prespecified before data collection. RESULTS: In this study, 102 patients were evaluated. Among them, 16.7% of patients in the study arm received no opioids up to 48 hours compared with 14.8% in the control arm (P=.99). There were no significant differences in the amount of intraoperative opioids administered or days to first opioid use. There was no significant difference between the 2 arms in median cumulative morphine equivalent daily dose (21.3 [study arm] vs 33.8 [control arm]; P=.36) or between the groups in morphine equivalent daily dose per individual day. There were no significant differences in patient-reported pain or interference with walking between the 2 arms or other patient-reported outcomes. CONCLUSION: Within an enhanced recovery after surgery pathway, adding liposomal bupivacaine to 0.25% bupivacaine wound infiltration did not decrease the proportion of patients who were opioid-free within 48 hours after surgery, did not decrease opioid intake, or did not improve patient's self-reported pain and functional recovery compared with standard bupivacaine.

OBJECTIVE: To examine the effect of anesthesia technique in an enhanced recovery after surgery (ERAS) pathway on post-operative opioid use. METHODS: Patients undergoing open gynecologic surgery under an ERAS pathway from November 2014 through December 2018 were included retrospectively. All patients received pre-operative analgesia consisting of oral acetaminophen, pregabalin, celecoxib, and tramadol extended release, unless contraindicated. Patients received local wound infiltration with bupivacaine; the post-operative analgesic regimen was standardized. Patients were categorized by anesthesia technique: (1) inhalational, (2) total intravenous anesthesia (TIVA), and (3) combined technique. The primary outcome was post-operative opioid consumption measured as morphine equivalent dose, recorded as the total opioid dose received post-operatively, including doses received through post-operative day 3. RESULTS: A total of 1184 patients underwent general anesthesia using either inhalational (386, 33%), TIVA (349, 29%), or combined (449, 38%) techniques. Patients who received combined anesthesia had longer surgery times (p=0.005) and surgical complexity was higher among patients who underwent TIVA (moderate/higher in 76 patients, 38%) compared with those who received inhaled anesthesia (intermediate/higher in 41 patients, 23%) or combined anesthesia (intermediate/higher in 72 patients, 30%). Patients who underwent TIVA anesthesia consumed less post-operative opioids than those managed with inhalational technique (0 (0-46.3) vs 10 (0-72.5), p=0.009) or combined anesthesia (0 (0-46.3) vs 10 (0-87.5), p=0.029). Similarly, patients who underwent the combined technique had similar opioid consumption post-operatively compared with those who received inhalational anesthesia (10 (0-87.5) vs 10 (0-72.5), p=0.34). CONCLUSIONS: TIVA technique is associated with a decrease in post-operative consumption of opioids after open gynecologic surgery in patients on an ERAS pathway.

A negative interim positron emission tomography/computerized tomography (PET/CT) after 1 to 3 cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) in patients with newly diagnosed, nonbulky stage I or II Hodgkin lymphoma (HL) predicts a low relapse rate. This phase 2 trial was designed to determine if a population of patients with early-stage disease can be treated with short-course ABVD without radiation therapy (RT) on the basis of a negative interim PET/CT, thereby limiting the risks of treatment. Between 15 May 2010 and 21 February 2013, 164 previously untreated patients with nonbulky stage I/II HL were enrolled, and 149 were included in the final analysis. Patients received 2 cycles of ABVD followed by PET. Deauville scores 1 to 3 were negative (≤ liver uptake) based on central review. PET- patients received 2 more cycles of ABVD, and PET+ patients received 2 cycles of dose-intense bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (escalated BEACOPP) plus 3060-cGy involved-field RT. The primary objective was to determine 3-year progression-free survival (PFS) for the PET- group. One hundred thirty-five patients (91%) were interim PET-, and 14 patients (9%) were PET+ With median follow-up time of 3.8 years, the estimated 3-year PFS was 91% for the PET- group and 66% for the PET+ group (hazard ratio, 3.84; 95% confidence interval, 1.50-9.84; P = .011). There was 1 death as a result of suicide. Four cycles of ABVD resulted in durable remissions for a majority of patients with early-stage nonbulky HL and a negative interim PET. This trial was registered at www.clinicaltrials.gov as #NCT01132807.

BACKGROUND: Enhanced recovery programs have been associated with improved outcomes after gynecologic surgery. There are limited data on the effect of enhanced recovery programs on healthcare costs or healthcare service use. OBJECTIVE: The purpose of this study was to evaluate differences in hospital charges for women who undergo surgery for a suspected gynecologic cancer that is managed in an enhanced recovery program as compared with conventional perioperative care. STUDY DESIGN: We performed a retrospective cohort study of women who underwent open abdominal surgery for a suspected gynecologic cancer before and after the implementation of an enhanced recovery after surgery program. Consecutive patients from May to October 2014 and from November 2014 to November 2015 comprised the conventional perioperative care (before enhanced recovery after surgery) and enhanced recovery after surgery cohorts, respectively. Patients were excluded if they underwent surgery with a multidisciplinary surgical team or minimally invasive surgery. All technical and professional charges were ascertained for all healthcare services from the day of surgery until postoperative day 30. Charges for adjuvant treatment were excluded. Charges were classified according to the type of clinical service provided. The primary outcome was the difference in total hospital charges between the pre-enhanced recovery after surgery and the enhanced recovery after surgery groups. Secondary outcomes were between group differences in hospital charges within clinical service categories. RESULTS: A total of 271 patients were included in the analysis (58 patients in the pre-enhanced recovery after surgery and 213 patients in the enhanced recovery after surgery cohort). A total of 70,177 technical charges and 6775 professional charges were identified and classified. The median hospital charge for a patient decreased 15.6% in the enhanced recovery after surgery group compared with the pre-enhanced recovery after surgery group (95% confidence interval, 5-24.5%; P=.008). Patients in the enhanced recovery after surgery group also had lower charges for laboratory services (20% lower; 95% confidence interval, 0--39%; P=.04), pharmacy services (30% lower; 95% confidence interval, 14--41%; P<.001), room and board (25% lower; 95% confidence interval, 20--47%; P=.005), and material goods (64% lower; 95% confidence interval, 44--81%; P<.001). No differences in charges were observed for perioperative services, diagnostic procedures, emergency department care, transfusion-related services, interventional radiology procedures, physical/occupational therapy, outpatient care, or other services. CONCLUSION: Hospital charges and healthcare service use were lower for enhanced recovery patients compared with patients who received conventional perioperative care after open surgery for a suspected gynecologic cancer. Enhanced recovery programs may be considered to be high value in healthcare because they provide improved outcomes while lowering resource use.

OBJECTIVE: To compare post-operative length of stay and complication rates of matched obese and non-obese patients in an enhanced recovery (ERAS) program after open gynecologic cancer surgery. METHODS: We performed an observational cohort study of patients (n=1225) undergoing open surgery from November 2014 to November 2018 at a tertiary cancer center. Patients undergoing multidisciplinary procedures, non-oncologic surgery, or procedures in addition to abdominal surgery were excluded (n=190). Obese and non-obese patients were matched by date, age, disease status, and surgical complexity. The primary outcome was post-operative length of stay. Secondary outcomes included 30-day peri-operative complications, re-operation, re-admission, opioid use, and program compliance. RESULTS: After matching, 696 patients (348 obese, 348 non-obese) with median age of 57 years (IQR 48-66) were analyzed. Obese patients had a longer median procedure time (218 min vs 192.5 min, p<0.001) and greater median estimated blood loss (300 mL vs 200 mL, p<0.001). Median (IQR) post-operative length of stay was the same for obese and non-obese patients: 3 days (IQR 2-4). Obese and non-obese patients had similar rates of grade III-IV complications (10.9% and 6.6%, respectively, p=0.06), re-operation (2.3% and 1.4%, respectively, p=0.58), and re-admission (11.8% and 8.0%, respectively, p=0.13). Grade I-II complications were more common among obese patients (62.4% vs 48.3%, p<0.001) because they had more wound complications (17.8% vs 4.9%, p<0.001). Obese patients received more opioids both during surgery (morphine equivalent dose 57.25 mg (IQR 35-72.5) vs 50 mg (IQR 25-622.5), p=0.003) and after surgery (morphine equivalent daily dose 45 mg/day (IQR 10-96.2) vs 29.37 mg/day (IQR 7.5-70), p=0.01). Obese and non-obese patients had similar ERAS program compliance (70.1% and 69.8%, respectively, p=0.32). CONCLUSIONS: Neither post-operative length of stay nor the rate of serious complications differed significantly despite longer surgeries, greater blood loss, and more opioid use among obese patients. An ERAS program was safe, effective, and feasible for obese patients with suspected gynecologic cancer.

Rituximab monotherapy has proven efficacy in treatment-naïve, asymptomatic advanced-stage follicular lymphoma (FL). Ofatumumab is a fully humanized anti-CD20 monoclonal antibody with increased CD20 affinity and complement-dependent cytotoxicity. This phase 2 trial (NCT01190449) evaluated ofatumumab in patients with untreated, low/intermediate-risk FL International Prognostic Index (FLIPI), advanced-stage FL to determine single-agent efficacy. Patients with measurable disease in stages III/IV or bulky stage II, regardless of Groupe d'Etude des Lymphomes Folliculaires criteria, received 4 weekly 1000 mg doses followed by four extended induction doses once every 8 weeks. Primary endpoint was overall response rate (ORR) to 1000 mg; secondary endpoints were progression-free survival (PFS) and safety. Fifty-one patients were enrolled. Fifteen patients were randomized to 500 mg prior to discontinuing that arm for slow accrual. Among 36 patients on the 1000 mg arm, ORR was 84%, median PFS was 1·9 years and median response duration was 23·7 months. All patients remain alive. No grade 4 infusion reactions or grade 3/4 infections occurred. Grade 3 infusion reactions occurred in 25% in the 1000 mg arm only (all first infusion); all but two patients continued on study. Discontinuation was 6% for the total study population. Ofatumumab monotherapy administered by extended induction in untreated, low/intermediate-risk FLIPI, advanced-stage FL is well tolerated and active. Activity appears similar to that reported with single-agent rituximab.

OBJECTIVES: To evaluate the prevalence and associated prognostic indicators in patients with vulvar carcinoma with and without evidence of perineural invasion (PNI). METHODS: A retrospective review identified 421 patients with invasive vulvar carcinoma evaluated at a single institution between 1993 and 2011. Medical records were reviewed for demographic data, pathologic information and presence or absence of PNI, treatment type, and recurrence/outcome information. Variables were compared between patients with PNI to those without PNI. RESULTS: Of the 421 patients included in the study, 32 (7.6%) had tumors with PNI. There were no significant differences in age, race/ethnicity, smoking history, histologic subtype, or grade between the group of patients with PNI and the group without PNI. The group with PNI was more likely to have lichen sclerosus (25.0% vs. 15.4%, pâ¯=â¯0.024), stage III/IV disease (59.4% vs. 36.0%, pâ¯=â¯0.007), lymph node involvement (50.0% vs. 21.6%, pâ¯=â¯0.002), and lymphovascular space invasion (LVSI) (53.1% vs. 15.9%, pâ¯<â¯0.001). A higher proportion of patients in the PNI group underwent primary or adjuvant radiation therapy (68.8% vs. 45.0%, pâ¯=â¯0.016). The median follow-up was 67.1â¯months (rangeâ¯<â¯1.0 to 284.3). Patients with PNI had significantly shorter overall survival (OS), median 25.5 vs. 94.3â¯months (pâ¯<â¯0.001), and progression-free survival (PFS), median 17.5 vs. 29.0â¯months (pâ¯=â¯0.004). After adjusting for stage, patients with PNI had a greater risk for death and progression (OS: hazard ratio, 2.71; pâ¯<â¯0.001; PFS: hazard ratio, 1.64; p-valueâ¯=â¯0.020). CONCLUSION: PNI should be considered an independent poor prognostic factor for patients with vulvar carcinoma, and should be included as part of the pathologic analysis.

OBJECTIVE: The aim of this study was to evaluate if varying levels of compliance with an enhanced recovery after surgery (ERAS) protocol impacted post-operative outcomes (length of stay, complications, readmissions, and re-operations) in gynecologic surgery at a tertiary center. METHODS: We included 584 patients who had open gynecologic surgery between November 1, 2014 and December 31, 2016. Patients were categorized into subgroups according to their date of surgery from the time of the ERAS protocol implementation. Patients were categorized by their per cent compliance into two groups:<80% versus ≥80%. We analyzed compliance with the elements of the protocol over time and its relation with post-operative outcomes, length of stay, post-operative complications, readmission, and re-operations rates. We modeled the probability of having a post-operative complication within 30 days of surgery as a function of overall compliance. RESULTS: Overall compliance was 72.3%. Patients with compliance ≥80% had significantly less complications (P<0.001) and shorter length of stay (P<0.001). Readmission and re-operation rates were not impacted by compliance (P=0.182, P=0.078, respectively). Avoidance of salt water overload, early mobilization, early oral nutrition, and early removal of Foley catheter were significantly associated with less post-operative complications within 30 days. CONCLUSIONS: Compliance with an ERAS pathway exceeding 80% was associated with lower complication rates and shorter length of stay without impacting on re-operations or readmissions.

Chemoimmunotherapy in follicular lymphoma is associated with significant toxicity. Targeted therapies are being investigated as potentially more efficacious and tolerable alternatives for this multiply-relapsing disease. Based on promising activity with rituximab and lenalidomide in previously untreated follicular lymphoma (overall response rate [ORR] 90%-96%) and ibrutinib in relapsed disease (ORR 30%-55%), the Alliance for Clinical Trials in Oncology conducted a phase 1 trial of rituximab, lenalidomide, and ibrutinib. Previously untreated patients with follicular lymphoma received rituximab 375 mg/m2 on days 1, 8, 15, and 22 of cycle 1 and day 1 of cycles 4, 6, 8, and 10; lenalidomide as per cohort dose on days 1 to 21 of 28 for 18 cycles; and ibrutinib as per cohort dose daily until progression. Dose escalation used a 3+3 design from a starting dose level (DL) of lenalidomide 15 mg and ibrutinib 420 mg (DL0) to DL2 (lenalidomide 20 mg, ibrutinib 560 mg). Twenty-two patients were enrolled; DL2 was determined to be the recommended phase II dose. Although no protocol-defined dose-limiting toxicities were reported, a high incidence of rash was observed (all grades 82%, grade 3 36%). Eleven patients (50%) required dose reduction, 7 because of rash. The ORR for the entire cohort was 95%, and the 12-month progression-free survival was 80% (95% confidence interval, 57%-92%). Five patients developed new malignancies; 3 had known risk factors before enrollment. Given the increased toxicity and required dose modifications, as well as the apparent lack of additional clinical benefit to the rituximab-lenalidomide doublet, further investigation of the regimen in this setting seems unwarranted. The study was registered with www.ClinicalTrials.gov as #NCT01829568.

PURPOSE: Tools to estimate survival, such as ePrognosis ( http://eprognosis.ucsf.edu/carey2.php ), were developed for general, not cancer, populations. In older patients with breast cancer, accurate overall survival estimates would facilitate discussions about adjuvant therapies. METHODS: Secondary analyses were performed of data from two parallel breast cancer studies (CALGB/Alliance 49907/NCT000224102 and CALGB/Alliance 369901/NCT00068328). We included patients (n = 971) who were age 70 years and older with complete baseline quality of life data (194 from 49907; 777 from 369901). Estimated versus observed all-cause two-year mortality rates were compared. ePrognosis score was calculated based on age, sex, and daily function (derived from EORTC QLQ-C30). ePrognosis scores range from 0 to 10, with higher scores indicating worse prognosis based on mortality of community-dwelling elders and were categorized into three groups (0-2, 3-6, 7-10). Observed mortality rates were estimated using Kaplan-Meier methods. RESULTS: Patient mean age was 75.8 years (range 70-91) and 73% had stage I-IIA disease. Most patients were classified by ePrognosis as good prognosis (n = 562, 58% 0-2) and few (n = 18, 2% 7-10) poor prognosis. Two-year observed mortality rates were significantly lower than ePrognosis estimates for patients scoring 0-2 (2% vs 5%, p = 0.001) and 3-6 (8% vs 12%, p = 0.01). The same trend was seen with scores of 7-10 (23% vs 36%, p = 0.25). CONCLUSIONS: ePrognosis tool only modestly overestimates mortality rate in older breast cancer patients enrolled in two cooperative group studies. This tool, which estimates non-cancer mortality risk based on readily available clinical information may inform adjuvant therapy decisions but should be validated in non-clinical trial populations.

BACKGROUND: The number of survivors of breast cancer aged ≥65 years ("older") is growing, but to the authors' knowledge, little is known regarding the cognitive outcomes of these individuals. METHODS: A cohort of cognitively intact older survivors with nonmetastatic, invasive breast cancer was recruited from 78 sites from 2004 through 2011; approximately 83.7% of the survivors (1280 survivors) completed baseline assessments. Follow-up data were collected at 6 months and annually for up to 7 years (median, 4.1 years). Cognitive function was self-reported using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30); scores ranged from 0 to 100, with a higher score indicating better function. Group-based trajectory modeling determined trajectories; women were assigned to a trajectory group based on the highest predicted probability of membership. Multinomial logistic regression evaluated the association between receipt of chemotherapy (with or without hormonal treatment) and trajectory group. RESULTS: Survivors were aged 65 to 91 years; approximately 41% received chemotherapy. There were 3 cognitive trajectories: "maintained high" (42.3% of survivors); "phase shift" (50.1% of survivors), with scores slightly below but parallel to maintained high; and "accelerated decline" (7.6% of survivors), with the lowest baseline scores and greatest decline (from 71.7 [standard deviation, 19.8] to 58.3 [standard deviation, 21.9]). The adjusted odds of being in the accelerated decline group (vs the maintained high group) were 2.1 times higher (95% confidence interval, 1.3-3.5) for survivors who received chemotherapy (with or without hormonal therapy) versus those treated with hormonal therapy alone. Greater comorbidity and frailty also were found to be associated with accelerated decline. CONCLUSIONS: Trajectory group analysis demonstrated that the majority of older survivors maintained good long-term self-reported cognitive function, and that only a small subset who were exposed to chemotherapy manifested accelerated cognitive decline. Future research is needed to determine factors that place some older survivors at risk of experiencing cognitive decline. Cancer 2016;122:3555-3563. © 2016 American Cancer Society.
RESUMO
Cognitive changes in older women receiving chemotherapy are poorly understood. We examined self-reported cognitive function for older women who received adjuvant chemotherapy on Cancer and Leukemia Group B (CALGB) 49907. CALGB 49907 randomized 633 women aged ≥65 with stage I-III breast cancer to standard adjuvant chemotherapy (cyclophosphamide-methotrexate-5-fluorouracil or doxorubicin-cyclophosphamide) versus capecitabine. We examined self-reported cognitive function in 297 women (CALGB 361002) who enrolled on the quality of life substudy and had no gross impairment on cognitive screening. Women were evaluated using an 18-item instrument at six time points (baseline through 24 months). At each time point for each patient, we calculated a cognitive function score (CFS) defined as the mean response of items 1-18 and defined impairment as a score >1.5 standard deviations above the overall average baseline score. Differences in scores by patient characteristics were evaluated using a Kruskal-Wallis test. A linear mixed-effects model was used to assess CFSs by treatment over time. Among 297 women, the median age was 71.5 (range 65-85) and 73 % had performance status of 0. Baseline depression and fatigue were reported in 6 and 14 % of patients, respectively. The average CFS at baseline was 2.08 (corresponding to "normal ability"), and baseline cognitive function did not differ by treatment regimen (p = 0.350). Over 24 months, women reported minimal changes at each time point and insignificant differences by treatment arm were observed. In a healthy group of older women, chemotherapy was not associated with longitudinal changes in self-reported cognitive function.

To identify a group of patients who might benefit from the addition of weekly paclitaxel to conventional anthracycline-containing chemotherapy as adjuvant therapy of node-positive operable breast cancer. The predictive value of PAM50 subtypes and the 11-gene proliferation score contained within the PAM50 assay were evaluated in 820 patients from the GEICAM/9906 randomized phase III trial comparing adjuvant FEC to FEC followed by weekly paclitaxel (FEC-P). Multivariable Cox regression analyses of the secondary endpoint of overall survival (OS) were performed to determine the significance of the interaction between treatment and the (1) PAM50 subtypes, (2) PAM50 proliferation score, and (3) clinical and pathological variables. Similar OS analyses were performed in 222 patients treated with weekly paclitaxel versus paclitaxel every 3 weeks in the CALGB/9342 and 9840 metastatic clinical trials. In GEICAM/9906, with a median follow up of 8.7 years, OS of the FEC-P arm was significantly superior compared to the FEC arm (unadjusted HR = 0.693, p = 0.013). A benefit from paclitaxel was only observed in the group of patients with a low PAM50 proliferation score (unadjusted HR = 0.23, p < 0.001; and interaction test, p = 0.006). No significant interactions between treatment and the PAM50 subtypes or the various clinical-pathological variables, including Ki-67 and histologic grade, were identified. Finally, similar OS results were obtained in the CALGB data set, although the interaction test did not reach statistical significance (p = 0.109). The PAM50 proliferation score identifies a subset of patients with a low proliferation status that may derive a larger benefit from weekly paclitaxel.

Follicular lymphoma (FL) is an indolent B-cell neoplasm of germinal center origin. Standard treatment regimens consist of anti-CD20 therapy with or without chemotherapy. While high response rates to initial therapy are common, patients ultimately relapse or have progressive disease. Clinical risk factors such as the Follicular Lymphoma International Prognostic Index (FLIPI) have been identified, but there is a need for prognostic and predictive biomarkers. We studied markers of lymphoma cells and tumor microenvironment by immunohistochemistry in tissue samples from patients enrolled in 1 of 4 phase 2 trials of anti-CD20-based biological therapy for previously untreated grades 1 to 2 or 3A FL. Results were correlated with progression-free survival (PFS) and PFS status at 24 months. The 4 trials included 238 patients (51.1% male, median age: 55 y) with stage III, IV, or bulky stage II disease. By FLIPI, 24.6% had low-risk, 56.8% had intermediate-risk, and 18.6% had high-risk disease. The outcome differed significantly for patients treated with lenalidomide and rituximab (CALGB 50803) compared with the other 3 trials (median: PFS not reached vs. 3.0 y, hazard ratio=3.47, 95% confidence interval: 2.11-5.72); therefore, data were stratified by clinical trial (CALGB 50803 vs. all others) and adjusted for FLIPI risk group. Among 154 patients with available tissue, interfollicular BCL6 positivity, interfollicular CD10 positivity, and elevated Ki67 proliferation index ≥30% within neoplastic follicles were each associated with inferior PFS and a high risk of the early event by PFS status at 24 months. We identify promising biomarkers for FL risk stratification that warrant further validation in phase 3 trials.

Evaluation of tolerability is increasingly relevant for patients with haematological malignancies treated with chronically administered therapies. Adverse events from these agents might affect the ability of patients to tolerate treatment over time. Conventional toxicity tables that include the incidence of high-grade adverse events, defined by the Common Terminology Criteria for Adverse Events, do not provide information on the time profile of these adverse events or reflect the continuous, lower grade symptomatic toxicities that are particularly relevant to treatment tolerability for patients living with indolent disease. Modern approaches to the evaluation and reporting of toxicity that capture the tolerability of treatment to the patient are imperative. In this Viewpoint, we present a focused, pilot, and longitudinal Toxicity over Time analysis of adverse events from lenalidomide and lenalidomide with rituximab in patients with follicular lymphoma treated in the CALGB 50401 (Alliance; NCT00238238) trial to define the trajectory of adverse events and quantify the burden of continuous, low-grade events. Toxicity over Time analyses provided clinically relevant descriptions of neutropenia and fatigue trajectories caused by lenalidomide that were not identified by standard analysis of the maximum grade events defined by the Common Terminology Criteria for Adverse Events. Systematic, rigorous incorporation of patient-reported outcomes in clinical trials will be crucial to our understanding of the tolerability of chronically administered therapies in patients with haematological malignancies.

Follicular lymphoma (FL) patients treated with firstline R-CHOP who experience progression of disease (POD) within 2 years have a shorter survival than those who do not have POD within 2 years. Whether this observation holds for patients treated initially with biologic immunotherapy alone is unknown. We performed a retrospective analysis of 174 patients pooled from three frontline rituximab (R)-based nonchemotherapy doublet trials: R-galiximab (Anti-CD80, CALGB 50402), R-epratuzumab (Anti-CD22, CALGB 50701), and R-lenalidomide (CALGB 50803) to determine outcomes of early progressors and risk factors for early POD, defined as progression within 24 months from study entry. Twenty-eight percent (48/174) of patients had early POD. After adjusting for the Follicular Lymphoma International Prognostic Index (FLIPI), patients with early POD from study entry had a worse OS compared with patients who did not progress within 2 years (HR = 4.33 (95% CI 1.50-12.5), P = 0.007). For early POD, the 2-year survival was 80% vs 99% for nonearly POD, and the 5-year survival was 74% vs 90%, respectively. These findings suggest that the adverse survival of patients with early POD may be independent of initial treatment modality.

PURPOSE: Alliance/CALGB 50303 (NCT00118209), an intergroup, phase III study, compared dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) with standard rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) as frontline therapy for diffuse large B-cell lymphoma. PATIENTS AND METHODS: Patients received six cycles of DA-EPOCH-R or R-CHOP. The primary objective was progression-free survival (PFS); secondary clinical objectives included response rate, overall survival (OS), and safety. RESULTS: Between 2005 and 2013, 524 patients were registered; 491 eligible patients were included in the final analysis. Most patients (74%) had stage III or IV disease; International Prognostic Index (IPI) risk groups included 26% IPI 0 to 1, 37% IPI 2, 25% IPI 3, and 12% IPI 4 to 5. At a median follow-up of 5 years, PFS was not statistically different between the arms (hazard ratio, 0.93; 95% CI, 0.68 to 1.27; P = .65), with a 2-year PFS rate of 78.9% (95% CI, 73.8% to 84.2%) for DA-EPOCH-R and 75.5% (95% CI, 70.2% to 81.1%) for R-CHOP. OS was not different (hazard ratio, 1.09; 95% CI, 0.75 to 1.59; P = .64), with a 2-year OS rate of 86.5% (95% CI, 82.3% to 91%) for DA-EPOCH-R and 85.7% (95% CI, 81.4% to 90.2%) for R-CHOP. Grade 3 and 4 adverse events were more common (P < .001) in the DA-EPOCH-R arm than the R-CHOP arm, including infection (16.9% v 10.7%, respectively), febrile neutropenia (35.0% v 17.7%, respectively), mucositis (8.4% v 2.1%, respectively), and neuropathy (18.6% v 3.3%, respectively). Five treatment-related deaths (2.1%) occurred in each arm. CONCLUSION: In the 50303 study population, the more intensive, infusional DA-EPOCH-R was more toxic and did not improve PFS or OS compared with R-CHOP. The more favorable results with R-CHOP compared with historical controls suggest a potential patient selection bias and may preclude generalizability of results to specific risk subgroups.

Purpose: We profiled circulating tumor cells (CTCs) to study the biology of blood-borne metastasis and to monitor biomarker status in metastatic breast cancer (MBC).Methods: CTCs were isolated from 105 patients with MBC using EPCAM-based immunomagnetic enrichment and fluorescence-activated cells sorting (IE/FACS), 28 of whom had serial CTC analysis (74 samples, 2-5 time points). CTCs were subjected to microfluidic-based multiplex QPCR array of 64 cancer-related genes (n = 151) and genome-wide copy-number analysis by array comparative genomic hybridization (aCGH; n = 49).Results: Combined transcriptional and genomic profiling showed that CTCs were 26% ESR1-ERBB2-, 48% ESR1+ERBB2-, and 27% ERBB2+ Serial testing showed that ERBB2 status was more stable over time compared with ESR1 and proliferation (MKI67) status. While cell-to-cell heterogeneity was observed at the single-cell level, with increasingly stable expression in larger pools, patient-specific CTC expression "fingerprints" were also observed. CTC copy-number profiles clustered into three groups based on the extent of genomic aberrations and the presence of large chromosomal imbalances. Comparative analysis showed discordance in ESR1/ER (27%) and ERBB2/HER2 (23%) status between CTCs and matched primary tumors. CTCs in 65% of the patients were considered to have low proliferation potential. Patients who harbored CTCs with high proliferation (MKI67) status had significantly reduced progression-free survival (P = 0.0011) and overall survival (P = 0.0095) compared with patients with low proliferative CTCs.Conclusions: We demonstrate an approach for complete isolation of EPCAM-positive CTCs and downstream comprehensive transcriptional/genomic characterization to examine the biology and assess breast cancer biomarkers in these cells over time.

Purpose: Response to a complex trastuzumab-based regimen is affected by multiple features of the tumor and its microenvironment. Developing a predictive algorithm is key to optimizing HER2-targeting therapy.Experimental Design: We analyzed 137 pretreatment tumors with mRNA-seq and DNA exome sequencing from CALGB 40601, a neoadjuvant phase III trial of paclitaxel plus trastuzumab with or without lapatinib in stage II to III HER2-positive breast cancer. We adopted an Elastic Net regularized regression approach that controls for covarying features within high-dimensional data. First, we applied 517 known gene expression signatures to develop an Elastic Net model to predict pCR, which we validated on 143 samples from four independent trials. Next, we performed integrative analyses incorporating clinicopathologic information with somatic mutation status, DNA copy number alterations (CNA), and gene signatures.Results: The Elastic Net model using only gene signatures predicted pCR in the validation sets (AUC = 0.76). Integrative analyses showed that models containing gene signatures, clinical features, and DNA information were better pCR predictors than models containing a single data type. Frequently selected variables from the multiplatform models included amplifications of chromosome 6p, TP53 mutation, HER2-enriched subtype, and immune signatures. Variables predicting resistance included Luminal/ER+ features.Conclusions: Models using RNA only, as well as integrated RNA and DNA models, can predict pCR with improved accuracy over clinical variables. Somatic DNA alterations (mutation, CNAs), tumor molecular subtype (HER2E, Luminal), and the microenvironment (immune cells) were independent predictors of response to trastuzumab and paclitaxel-based regimens. This highlights the complexity of predicting response in HER2-positive breast cancer. Clin Cancer Res; 24(21); 5292-304. ©2018 AACR.
