ABSTRACT

Immune evasion, due to abnormal expression of programmed-death ligands 1 and 2 (PD-L1/PD-L2), predicts poor outcomes with chemoimmunotherapy in diffuse large B-cell lymphoma (DLBCL). Immune checkpoint inhibition (ICI) has limited efficacy at relapse but may sensitise relapsed lymphoma to subsequent chemotherapy. ICI delivery to immunologically intact patients may thus be the optimal use of this therapy. In the phase II AvR-CHOP study, 28 patients with treatment-naive stage II-IV DLBCL received sequential avelumab and rituximab priming ("AvRp;" avelumab 10 mg/kg and rituximab 375 mg/m2 2-weekly for 2 cycles), R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone for 6 cycles) and avelumab consolidation (10 mg/kg 2-weekly for 6 cycles). Grade 3/4 immune-related adverse events occurred in 11%, meeting the primary endpoint of a grade ≥3 irAE rate of <30%. R-CHOP delivery was not compromised but one patient ceased avelumab. Overall response rates (ORR) after AvRp and R-CHOP were 57% (18% CR) and 89% (all CR). High ORR to AvRp was observed in primary mediastinal B-cell lymphoma (67%; 4/6) and molecularly-defined EBV-positive DLBCL (100%; 3/3). Progression during AvRp was associated with chemorefractory disease. Two-year failure-free and overall survival were 82% and 89%. An immune priming strategy with AvRp, R-CHOP and avelumab consolidation shows acceptable toxicity with encouraging efficacy.

ABSTRACT

BACKGROUND AND PURPOSE: The chemotherapy exposure during chemoradiotherapy for rectal cancer is adequate for radiosensitization but suboptimal for treatment of distant micrometastasis. This study aimed to determine tolerability, dose intensity, response, and toxicity of a novel intensified neoadjuvant treatment approach. MATERIALS AND METHODS: Eligible patients were MRI-staged T3-4NxM0 rectal adenocarcinoma. Treatment consisted of FOLFOX chemotherapy given in weeks 1, 6, and 11 with pelvic radiotherapy (25.2 Gy in 3 weeks in 1.8 Gy/fraction with oxaliplatin and 5-FU continuous infusion) given in weeks 3-5, and weeks 8-10. Surgery was performed 4-6 weeks later. The primary endpoint was tolerability defined as the percentage of patients who were able to complete the planned treatment course. Survival rates were estimated using the Kaplan-Meier method. RESULTS: Median age of the 40 patients was 61.5 years. Rectal MRI-stage was T3 in 88%. Overall, 95% completed the regimen. All patients received 50.4 Gy. Relative dose intensity (≥75%) was 92% and 98% for oxaliplatin and 5-FU, respectively. High grade toxicities included neutropenia (25% grade 3; 7.5% grade 4) and diarrhoea (10%). Pathologic CR rate was 20%. Median follow-up was 54 months. The 5-year overall survival, freedom from relapse, locoregional control, and freedom from distant metastasis of the cohort was 82%, 72%, 97% and 72%. CONCLUSIONS: Delivery of intensified neoadjuvant treatment with interdigitating chemotherapy and radiotherapy is feasible with no increase in acute perioperative complications. A larger prospective study is required to further evaluate the potential survival benefit of this design.

ABSTRACT

BACKGROUND: In the treatment of metastatic colorectal cancer (mCRC), exposure to all three active cytotoxic agents, 5-fluorouracil/capecitabine, irinotecan and oxaliplatin, improves overall survival. The addition of biologic agents (bevacizumab and cetuximab/panitumumab) further improves survival. The uptake of available systemic agents for mCRC in routine practice in Australia is poorly described. METHODS: The ACCORD database was interrogated to determine demographics, treatments and outcomes for patients diagnosed with mCRC between 1 January 2011 and 1 January 2016 at six Melbourne centres. RESULTS: About 1130 mCRC patients were identified: median age was 69 years (range 26-105); 61% had synchronous disease. KRAS status was known in 62%, of whom 49% were KRAS wild-type. At the time of analysis, 67% of all patients had commenced systemic treatment, 50% had received two or more lines of therapy and 19% of KRAS wild-type patients had received all five active drugs. Of KRAS-mutated patients, 35% had received all four Pharmaceutical Benefits Scheme-reimbursed active drugs. Patients who had not received chemotherapy included 72 patients who underwent metastasectomy alone. At a median follow up of 34 months, median overall survival was 25 months for all patients and 69 months for those who underwent metastasectomy. CONCLUSION: In this community-based cohort, 33% of patients had not received any systemic therapy for mCRC, and few patients had received all available active systemic agents. As many patients remain alive, these figures will likely increase over time. The overall survival of patients with mCRC in this community-based cohort was 25 months and not dissimilar to that achieved in recent clinical trials.

ABSTRACT

Importance: Adjuvant chemotherapy in patients with stage III colon cancer prevents recurrence by eradicating minimal residual disease. However, which patients remain at high risk of recurrence after completing standard adjuvant treatment cannot currently be determined. Postsurgical circulating tumor DNA (ctDNA) analysis can detect minimal residual disease and is associated with recurrence in colorectal cancers. Objective: To determine whether serial postsurgical and postchemotherapy ctDNA analysis could provide a real-time indication of adjuvant therapy efficacy in stage III colon cancer. Design, Setting, and Participants: This multicenter, Australian, population-based cohort biomarker study recruited 100 consecutive patients with newly diagnosed stage III colon cancer planned for 24 weeks of adjuvant chemotherapy from November 1, 2014, through May 31, 2017. Patients with another malignant neoplasm diagnosed within the last 3 years were excluded. Median duration of follow-up was 28.9 months (range, 11.6-46.4 months). Physicians were blinded to ctDNA results. Data were analyzed from December 10, 2018, through June 23, 2019. Exposures: Serial plasma samples were collected after surgery and after chemotherapy. Somatic mutations in individual patients' tumors were identified via massively parallel sequencing of 15 genes commonly mutated in colorectal cancer. Personalized assays were designed to quantify ctDNA. Main Outcomes and Measures: Detection of ctDNA and recurrence-free interval (RFI). Results: After 4 exclusions, 96 eligible patients were eligible; median patient age was 64 years (range, 26-82 years); 49 (51%) were men. At least 1 somatic mutation was identified in the tumor tissue of all 96 evaluable patients. Circulating tumor DNA was detectable in 20 of 96 (21%) postsurgical samples and was associated with inferior recurrence-free survival (hazard ratio [HR], 3.8; 95% CI, 2.4-21.0; P < .001). Circulating tumor DNA was detectable in 15 of 88 (17%) postchemotherapy samples. The estimated 3-year RFI was 30% when ctDNA was detectable after chemotherapy and 77% when ctDNA was undetectable (HR, 6.8; 95% CI, 11.0-157.0; P < .001). Postsurgical ctDNA status remained independently associated with RFI after adjusting for known clinicopathologic risk factors (HR, 7.5; 95% CI, 3.5-16.1; P < .001). Conclusions and Relevance: Results suggest that ctDNA analysis after surgery is a promising prognostic marker in stage III colon cancer. Postchemotherapy ctDNA analysis may define a patient subset that remains at high risk of recurrence despite completing standard adjuvant treatment. This high-risk population presents a unique opportunity to explore additional therapeutic approaches.

ABSTRACT

A 67-year-old man with an 11-year history of composite lymphoma was admitted with fevers in the context of neutropenia and acute liver injury, 4 months after the commencement of single-agent brentuximab vedotin. Fevers resolved with intravenous antibiotics, however, his liver function tests remained abnormal and he continued to be deeply jaundiced over the course of his 3-week illness. A liver screen failed to indicate a cause for his liver function test abnormalities and two separate liver biopsies were suggestive of drug-induced liver injury. There was no evidence on biopsy of lymphoma. After consultation with two hepatologists, trials of steroids and ursodeoxycholic acid were unsuccessful. Twenty-five days into admission, he became septic with a normal peripheral blood count and deteriorated rapidly. After discussion with the family, he was deemed not to be for further escalation of care, and he died within several hours. This report summarizes the evidence in relation to hepatotoxicity of brentuximab vedotin.

ABSTRACT

PURPOSE: Testicular seminomas occur in young men and are highly curable. Toxicities following treatment for men with extensive stage II-III seminomas may cause long-term morbidities. However, it is not clear whether the risk of late effects also increases following surgery for testis-confined seminoma. In this systematic review, we examined the available literature regarding the incidence of late effects in our target population of patients with stage I seminoma treated with orchidectomy alone. METHOD: Publications were identified through an electronic literature search using the MEDLINE, EMBASE and PsychInfo databases, identifying cohorts treated for stage I seminoma. Data on late effects were collected and classified as physical or psychological. RESULTS: Six hundred and four articles were screened to identify 100 studies. In the target population, available evidence suggests no increased risk of cardiovascular disease, metabolic syndrome, or renal dysfunction compared to the general population. Sperm counts were initially lower than an age-matched cohort; however, counts normalised when re-assessed 5 years later. Data were not specifically reported for the target population regarding bone health, second malignancy, hypogonadism, fertility and all psychological domains. Heterogeneity of study design and reporting methods contributed to uncertainty regarding the true incidence and clinical significance of late effects. CONCLUSIONS: The curability of stage I seminoma and the wide range of potential late effects of treatment suggest the need for long-term monitoring alongside standard cancer surveillance. Important data are needed on the prevalence of late effects, specifically related to testicular cancer survivors undergoing surveillance following orchidectomy. IMPLICATIONS FOR CANCER SURVIVORS: Awareness and screening for relevant late effects may prevent further morbidity in men treated for stage I seminoma.

ABSTRACT

The title compound, C22H22OS [systematic name: 4-(1,3,3-trimethyl-2,3-di-hydro-1H-4-thia-phenanthren-1-yl)phenol], crystallizes unsolvated from nitro-methane as colourless prisms (m.p. 425-427 K) in the polar monoclinic space group Ia with Z' = 2 (mol-ecules A and B). Both independent mol-ecules possess a very similar proximal conformation, this referring to the juxtaposition of the 4-hy-droxy-phenyl substituent with respect to the syn-related methyl group. In the crystal, mol-ecule A is linked to mol-ecule B by an O-H⋯O hydrogen bond. In turn, mol-ecule B exhibits a weak O-H⋯π inter-action with the phenolic group of mol-ecule A related by a-glide symmetry. Together, these lead to [100] chains.

ABSTRACT

Posterior reversible encephalopathy syndrome (PRES) has been described in the context of uncontrolled hypertension, eclampsia, renal disease and autoimmune conditions, or in patients treated with chemotherapy or immunosuppressive agents. In contrast, we report the occurrence of PRES in a patient with untreated metastatic transitional cell carcinoma. The case emphasizes important diagnostic challenges associated with atypical presentations without "typical" risk factors and the limitations of common diagnostic imaging modalities. It highlights the ability of nonmalignant conditions like PRES to mimic brain metastases and the importance of magnetic resonance imaging as a diagnostic tool. A high index of suspicion is warranted in atypical presentations, as prompt treatment is imperative to ensure full neurological recovery.

ABSTRACT

BACKGROUND: Recent data has created uncertainty regarding the benefit of adjuvant fluoropyrimidine-containing chemotherapy following preoperative chemoradiotherapy and surgical resection for locally advanced rectal cancer (LARC). In particular, patients with a pathologic complete response (pCR) may derive no benefit from adjuvant chemotherapy. PATIENTS AND METHODS: This is a retrospective analysis of patients with LARC, diagnosed between January 1, 2003 and December 31, 2014 at 3 Melbourne health services. Patients were identified from the Australian Comprehensive Cancer Outcomes and Research Database, where a defined data set is prospectively collected on consecutive patients. Patient demographics, pCR rates, postoperative treatment, recurrence, and survival were analyzed. RESULTS: A total of 717 patients with LARC were identified, of whom 555 (77%) had received preoperative long-course chemoradiation followed by surgery. Four hundred fifty-two of 555 patients (81%) subsequently received adjuvant fluoropyrimidine-based chemotherapy. At a median follow-up of 45.9 months, 95 (21%) patients in the adjuvant chemotherapy group and 20 (19%) in the surveillance group had relapsed. Five-year relapse-free survival was 77% in the adjuvant chemotherapy group and 71% in the surveillance group with no significant difference on univariate analysis (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.58-1.51; P = .780). No significant impact on relapse-free survival was seen for either pCR or non-pCR patients. Five-year overall survival (OS) was 85% in the adjuvant chemotherapy group and 74% in the surveillance group with a nonsignificant trend towards OS benefit (HR, 0.62; 95% CI, 0.37-1.05; P = .074). A significant OS benefit favoring adjuvant chemotherapy was seen in the non-pCR subset of patients (HR, 0.49; 95% CI, 0.28-0.86; P = .014). CONCLUSION: A high proportion of patients in this routine practice cohort received adjuvant chemotherapy following preoperative treatment and surgery for LARC. Adjuvant chemotherapy administration was associated with a significant improvement in 5-year OS only in the patients with a non-pCR.

ABSTRACT

AIM: Relapsed/refractory (R/R) aggressive lymphoma outcomes are poor. There is no standard treatment. PACEBOM (prednisolone, doxorubicin, cyclophosphamide, etoposide, bleomycin, vincristine and methotrexate) has shown efficacy for several lymphoma subtypes in published reports. We evaluate PACEBOM+/-rituximab for R/R aggressive lymphomas in this millennium. METHODS: In this retrospective, single-center study, R/R aggressive lymphoma patients who received PACEBOM or its derivatives were identified from the pharmacy database. Demographic, treatment, toxicity and survival data were collected. RESULTS: A total of 37 eligible patients were identified. Histological subtypes included 20 Diffuse Large B-Cell Lymphoma (DLBCL), 10 T-Cell Lymphoma (TCL) and 7 Hodgkin lymphoma. All DLBCL patients had received prior rituximab. Thirty-one (84%) received second-line PACEBOM. Median number of cycles was six (1-6). Eighteen out of 20 B-cell lymphoma patients received R-PACEBOM. Overall response rate was 65%, 70% and 71% in patients with DLBCL, TCL and Hodgkin lymphoma respectively. Thirteen patients underwent autologous stem cell transplant post-PACEBOM. Median follow-up was 49 months (3-201). Most common grade 3-4 toxicities were neutropenia (46%), anemia (24%) and thrombocytopenia (16%). No additional toxicity was seen in patients who received rituximab. CONCLUSION: In this cohort, PACEBOM is active in R/R aggressive lymphoma with manageable toxicity and can be safely combined with rituximab. Outcomes were similar to reports of other salvage regimens. PACEBOM remains a suitable option for R/R aggressive lymphoma, in patients exposed to prior rituximab and those planned for autologous stem cell transplant.

ABSTRACT

PURPOSE: To assess health-related quality of life (HRQOL) in patients participating in a randomised trial of neoadjuvant short course radiation (SC) or long course chemoradiation (LC) for operable rectal cancer. PATIENTS AND METHODS: Eligible patients with T3N0-2M0 rectal cancer completed the European Organisation for Research and Treatment of Cancer quality of life questionnaire (QLQ-C30) and the colorectal cancer specific module (QLQ C38) at randomisation and 1, 2, 3, 6, 9 and 12 months later. RESULTS: Of 326 patients randomised, 297 (SC 143, LC 154) were eligible for completion of HRQOL questionnaires. Baseline scores were comparable across the SC and LC groups. Patients reported low scores on sexual functioning and sexual enjoyment. Defaecation problems were the worst of the symptoms at baseline. Surgery had the most profoundly negative effect on HRQOL, seen in both the SC and LC treatment groups to the same extent. The most severely affected domains were physical function and role function and the most severely affected symptoms were fatigue, pain, appetite, weight loss and male sexual problems. Most domains and symptoms returned to baseline levels by 12 months apart from body image, sexual enjoyment and male sexual problems. Future perspective was better than prior to treatment. CONCLUSION: There is no overall difference in HRQOL between SC and LC neoadjuvant treatment strategies, in the first 12 months, after surgery. In the immediate postoperative period HRQOL was adversely affected in both groups but for the most part was temporary. Some residual sexual functioning concerns persisted at 12 months.

ABSTRACT

The aim of this post hoc analysis of the VELOUR study (ClinicalTrials.gov NCT00561470) was to investigate the treatment effect of adding aflibercept to second-line infusional 5-fluorouracil (5-FU), leucovorin and irinotecan (FOLFIRI) in patients with metastatic colorectal cancer (mCRC) who had failed any prior oxaliplatin-containing regimen. Adjuvant rapid relapsers (ARR), who were enrolled directly following relapse during or within 6 months of completion of oxaliplatin-containing adjuvant chemotherapy (N = 124, including 17 patients who also received bevacizumab as part of their adjuvant therapy), were excluded from the original VELOUR intention-to-treat (ITT) population (N = 1226). After exclusion of the ARR, overall survival (OS) in the ITT minus ARR (ITT-ARR) population (N = 1102) was longer in the aflibercept plus FOLFIRI arm than in the placebo plus FOLFIRI arm [hazard ratio (HR) 0.78, 95 % confidence interval (CI) 0.68-0.90; median survival difference 1.87 months]. In the subgroup of patients assigned to the prior bevacizumab stratum at randomization, OS was numerically longer in the aflibercept plus FOLFIRI arm than in the placebo plus FOLFIRI arm (HR 0.81; 95 % CI 0.63-1.04; median survival difference 2.14 months). Comparison of the post hoc analysis results with the primary analysis from VELOUR suggests that the inclusion of the directly enrolled ARR may have understated the aflibercept treatment benefit for both bevacizumab-pretreated and bevacizumab-naïve patients in the strictly second-line setting although no definitive conclusion may be inferred. The benefit associated with the addition of aflibercept to second-line FOLFIRI in patients with mCRC was observed whatever the timing of first-line disease progression. There were no unexpected safety concerns.

ABSTRACT

AIMS: Defining multidisciplinary quality of care indicators (QCIs) for metastatic colorectal cancer (mCRC) could improve understanding of variations in routine practice care. This may identify areas of below-average performance, which could then be addressed by clinicians to improve the quality of care delivered. This study aimed to define a panel of QCIs in mCRC and, based on these QCIs, to evaluate quality of care across multiple Australian sites. METHODS: A panel of clinicians with expertise in colorectal cancer defined evidence-based or best practice-based QCIs relevant to the routine multidisciplinary management of mCRC patients through structured consensus discussion. Related data were extracted from the Treatment of Recurrent and Advanced Colorectal Cancer (TRACC) registry, a prospectively maintained database recording comprehensive details on consecutive mCRC patients across multiple Australian hospitals. Variations in QCIs across sites were explored. RESULTS: Of 13 QCIs defined, data related to 10 were reliably extracted from TRACC. Analysis of data on 1276 patients across 10 sites demonstrated low rates of screening for hereditary nonpolyposis colorectal cancer in young patients and significant variation in surveillance-detected recurrences, lung resection rates and palliative chemotherapy use. Exploratory analyses suggested correlation between liver resection rates and survival. CONCLUSIONS: We have defined a novel set of mCRC QCIs and have demonstrated wide variation in the quality of care of mCRC across multiple Australian sites. With further validation to confirm a direct correlation between QCI and patient outcomes, these QCIs could be applied to improve the quality of care received by all mCRC patients.

ABSTRACT

BACKGROUND: Patients with metastatic colorectal cancer (mCRC) previously-treated with oxaliplatin benefit significantly from the addition of aflibercept to FOLFIRI in relation to overall survival, progression-free survival and response rate. PATIENTS AND METHODS: The results for efficacy and safety over the time course of the VEGF Trap (aflibercept) with irinotecan in colorectal cancer after failure of oxaliplatin regimen trial were analysed based on data from 1226 patients randomised to receive FOLFIRI plus either aflibercept (n=612) or placebo (n=614). Hazard ratios (HR) by 6-month time period were estimated using a piecewise Cox proportional hazard model. Severity of adverse events (AEs) was graded using National Cancer Institute Common Terminology Criteria, version 3.0. RESULTS: The estimated probabilities of survival were 38.5% versus 30.9% at 18 months, 28.0% versus 18.7% at 24 months and 22.3% versus 12.0% at 30 months, for the aflibercept- and placebo-treated arms, respectively. The proportional improvement in the HR over time was consistent with the survival probability results; survival at 24 months was improved by 50% and almost doubled at 30 months. The majority of worst-grade AEs occurred within the first four cycles of treatment and in a small percent of treatment cycles and were mostly reversible. Common chemotherapy- and anti-vascular epithelial growth factor (VEGF)-associated AEs occurred rarely and in a small proportion of cycles with the majority being of single occurrence. CONCLUSIONS: The addition of aflibercept to FOLFIRI showed a continued and persistent improvement in overall survival over time in patients with mCRC. Although grade 3-4 AEs were more frequent in the aflibercept arm, they occurred in early treatment cycles and decreased sharply following initial presentation.

ABSTRACT

PURPOSE: The antiangiogenic agent aflibercept (ziv-aflibercept in the United States) in combination with 5-fluorouracil, leucovorin and irinotecan (FOLFIRI) significantly improved survival in a phase III study of patients with metastatic colorectal cancer (mCRC) previously treated with an oxaliplatin-based regimen. In the present analysis, outcomes were evaluated in prespecified subgroups to assess the consistency of the treatment effect. METHODS: Patients were randomised to receive FOLFIRI plus aflibercept or placebo every 2weeks until disease progression or unacceptable toxicity occurred. Efficacy and safety outcomes were analysed with respect to demographic and baseline characteristics, and stratification factors (prior bevacizumab treatment and Eastern Cooperative Oncology Group performance status). RESULTS: Median overall survival (OS, months [95.34% confidence interval (CI)]) for aflibercept versus placebo was 12.5 (10.8-15.5) versus 11.7 (9.8-13.8) in patients with prior bevacizumab treatment and 13.9 (12.7-15.6) versus 12.4 (11.2-13.5) in patients with no prior bevacizumab treatment. The p value for interaction was 0.5668, indicating there was no heterogeneity in these subgroups. For OS and progression-free survival (PFS), there was a significantly greater benefit (at the 2-sided 10% level) of treatment for patients with liver only metastases versus patients with no liver metastases/liver metastases with other organ involvement (p value for interaction: 0.0899 [OS]; 0.0076 [PFS]). There was no evidence of heterogeneity in treatment effect in any of the other subgroups examined. CONCLUSIONS: The benefits of aflibercept in combination with FOLFIRI in patients with mCRC previously treated with oxaliplatin were maintained across the specified patient subgroups, including in patients with or without prior bevacizumab treatment.

ABSTRACT

Adrenocortical carcinomas (ACCs) are rare and often aggressive with more than 50% of the cases already in stage III-IV (ENSAT) at the time of diagnosis. Nearly 60% of ACCs present with hormone overproduction syndromes (Cushing's syndrome and/or virilization), while the rest present with abdominal mass or incidental finding. Aggressive surgical resection is the mainstay of treatment usually followed by adjuvant mitotane monotherapy. For the advanced stage, adjuvant radiotherapy and combined chemotherapy with mitotane therapy can be added for survival benefit. Here, we would like to report a case of stage III high-grade ACC without syndromes of hormone overproduction, initially presented with pulmonary embolism. It was rapidly progressive with metastases to lungs, peritoneum and bone despite aggressive surgery followed by adjuvant mitotane monotherapy. However, after palliative radiotherapy to thoraco-lumbar spine for spinal cord compression, and adding chemotherapy (six cycles of EDP: etoposide, doxorubicin, cisplatin) to mitotane, a significant partial remission was achieved. He has had 24 months of progression-free survival, and is currently on mitotane monotherapy with cortisol replacement. Discussion will support multimodality therapy for stage III high-grade ACC with surgery immediately followed by adjuvant radiotherapy and combined chemotherapy with mitotane therapy to prevent local recurrence and distant metastases.

ABSTRACT

PURPOSE: To compare the local recurrence (LR) rate between short-course (SC) and long-course (LC) neoadjuvant radiotherapy for rectal cancer. PATIENTS AND METHODS: Eligible patients had ultrasound- or magnetic resonance imaging-staged T3N0-2M0 rectal adenocarcinoma within 12 cm from anal verge. SC consisted of pelvic radiotherapy 5 × 5 Gy in 1 week, early surgery, and six courses of adjuvant chemotherapy. LC was 50.4 Gy, 1.8 Gy/fraction, in 5.5 weeks, with continuous infusional fluorouracil 225 mg/m(2) per day, surgery in 4 to 6 weeks, and four courses of chemotherapy. RESULTS: Three hundred twenty-six patients were randomly assigned; 163 patients to SC and 163 to LC. Median potential follow-up time was 5.9 years (range, 3.0 to 7.8 years). Three-year LR rates (cumulative incidence) were 7.5% for SC and 4.4% for LC (difference, 3.1%; 95% CI, -2.1 to 8.3; P = .24). For distal tumors (< 5 cm), six of 48 SC patients and one of 31 LC patients experienced local recurrence (P = .21). Five-year distant recurrence rates were 27% for SC and 30% for LC (log-rank P = 0.92; hazard ratio [HR] for LC:SC, 1.04; 95% CI, 0.69 to 1.56). Overall survival rates at 5 years were 74% for SC and 70% for LC (log-rank P = 0.62; HR, 1.12; 95% CI, 0.76 to 1.67). Late toxicity rates were not substantially different (Radiation Therapy Oncology Group/European Organisation for Research and Treatment of Cancer G3-4: SC, 5.8%; LC, 8.2%; P = .53). CONCLUSION: Three-year LR rates between SC and LC were not statistically significantly different; the CI for the difference is consistent with either no clinically important difference or differences in favor of LC. LC may be more effective in reducing LR for distal tumors. No differences in rates of distant recurrence, relapse-free survival, overall survival, or late toxicity were detected.

ABSTRACT

PURPOSE: To report the results of a planned safety analysis from a phase III trial comparing capecitabine plus oxaliplatin (XELOX) with bolus fluorouracil/leucovorin (FU/LV) as adjuvant therapy for stage III colon cancer. PATIENTS AND METHODS: Patients with stage III colon carcinoma were randomly assigned to receive either XELOX (intravenous oxaliplatin plus oral capecitabine; 3-week cycle for eight cycles) or standard intravenous bolus FU/LV administered as the Mayo Clinic (Mayo; Rochester, MN) or Roswell Park (RP; Buffalo, NY) regimen for a similar length of time. A total of 1,886 patients were randomly assigned. RESULTS: The safety population comprised 1,864 patients, of whom 938 received XELOX and 926 received FU/LV. Most treatment-related adverse events (AEs) occurred at similar rates in both treatment arms. However, patients receiving XELOX experienced less all-grade diarrhea, alopecia, and more neurosensory toxicity, vomiting, and hand-foot syndrome than those patients receiving FU/LV. Compared with Mayo, XELOX showed fewer grade 3/4 hematologic AE and more grade 3/4 gastrointestinal AE. Compared with RP, XELOX showed less grade 3/4 gastrointestinal AE and more grade 3/4 hematologic AE. As expected grade 3/4 neurosensory toxicity and grade 3 hand-foot syndrome were higher with XELOX. Treatment-related mortality within 28 days from the last study dose was 0.6% in the XELOX group and 0.6% in the FU/LV group. CONCLUSION: XELOX has a manageable tolerability profile in the adjuvant setting. Efficacy data will be available within the next 24 months.
