PURPOSE: To determine the long-term disease-specific survival (DSS) and disease-free survival (DFS) rates after salvage cryotherapy for locally recurrent adenocarcinoma of the prostate and to identify pretreatment factors that have an impact on DSS and DFS. PATIENTS AND METHODS: Between July 1992 and January 1995, 131 patients who had received definitive radiation therapy (XRT) underwent salvage cryotherapy for locally recurrent adenocarcinoma of the prostate. Cryotherapy failure was defined as an increasing postcryotherapy prostate-specific antigen (PSA) level of ≥ 2 ng/mL above the postcryotherapy nadir, a positive prostate biopsy, or radiographic evidence of metastatic disease. Clinical variables were studied to determine whether there was an association with the DSS and DFS. RESULTS: The median follow-up was 4.8 years. The 5-year DSS rates were 87% for patients with a precryotherapy Gleason score ≤ 8 and 63% for those with Gleason scores of 9 and 10 (P = .012). The 5-year DFS rates were 57% for patients with a precryotherapy PSA level of ≤ 10 ng/mL and 23% for those with a PSA level greater than 10 ng/mL (P = .0004). The 5-year DSS rates for patients with a pre-XRT clinical stage of T1 to T2 and those with a clinical stage of T3 to T4 were 94% and 72%, respectively (P = .0041). The 5-year DFS rates for these groups were 90% and 69%, respectively (P = .0057). CONCLUSION: Androgen-independent local recurrences, Gleason score, and pre-XRT clinical stage were important factors that had an impact on DSS and DFS. The subset of patients cured by salvage cryotherapy seems to be small, and patient selection is important.

108 Background: The optimum treatment of Prostate cancer recurrence following external bean radiation therapy (EBRT) remains a controversial topic. The primary problem with comparing salvage techniques following EBRT is the lack of long term data. We reviewed the long- term overall survival, disease-specific survival and disease free survival of patients who have undergone salvage cryotherapy to the prostate gland. Methods: A retrospective analysis was performed on all patients undergoing salvage cryotherapy for locally recurrent prostate cancer after EBRT by a single surgeon at a single institution from 1995-2004. Patients preoperative, perioperative and postoperative data was reviewed and recorded. Should a patient no longer be followed by the urology service the Patients and the patient's primary care physician or urologist were contacted. Mortality data, PSA results, bone scan results and any details of hormone therapy were recorded for this study. Results: 187 patients were included in the current study from which 176 patients had records available for follow up giving a follow up rate of 94%. Mean follow up was 7.46 years (1-14 years). 52 patients were followed for greater than 10 years. Average time to prostate cancer recurrence in patients who developed recurred was 2.3 years and average time to hormone therapy in these patients was 2.8 years. Overall survival at 10 years was high at 87%. Risk factors for recurrence of tumour identified were presalvage PSA, preradiation and presalvage gleason score. Preradiation gleason score had little impact on survival. PSA nadir of >1.0ng/mL was highly predictive of early recurrence. Disease-free survival rates of between 39 and 64% depending on risk factors. Conclusions: Cryotherapy has a definite role in the management of prostate cancer, representing a minimally invasive salvage treatment with acceptable 10 year disease free survival (DFS) of upwards of 39% and specific groups attaining 10 year DFS of 64%. Presalvage PSA and Gleason score are the best predictors of disease recurrence, whilst preradiation gleason score did not correlate with risk of disease recurrence. A PSA Nadir greater than 1 ng/mL indicates a poor prognosis in which early ADT should be strongly considered. No significant financial relationships to disclose.

PURPOSE: Our objective was to identify clinical pretreatment factors associated with early treatment failure after salvage cryotherapy. PATIENTS AND METHODS: Between 1992 and 1995, 145 patients underwent salvage cryotherapy for locally recurrent adenocarcinoma of the prostate. Treatment failure was defined as an increasing postcryotherapy serial prostate-specific antigen (PSA) level of more than or equal to 2 ng/mL above the postcryotherapy nadir or as a positive posttreatment biopsy. We evaluated the following factors as predictors of treatment failure: tumor stage and grade at initial diagnosis, type of prior therapy, stage and grade of locally recurrent tumor, number of positive biopsy cores at recurrence, and precryotherapy PSA level. RESULTS: Among patients with a prior history of radiation therapy only, the 2-year actuarial disease-free survival (DFS) rates were 74% for patients with a precryotherapy PSA less than 10 ng/mL and 28% for patients with a precryotherapy PSA more than 10 ng/mL, P < .00001. The DFS rates were 58% for patients with a Gleason score of less than or equal to 8 recurrence and 29% for patients with a Gleason score greater than or equal to 9 recurrence, P < .004. Among patients with a precryotherapy PSA less than 10 ng/mL, DFS rates were 74% for patients with a prior history of radiation therapy only and 19% for patients with a history of prior hormonal therapy plus radiation therapy, P < .002. CONCLUSION: Patients failing initial radiation therapy with a PSA more than 10 ng/mL and Gleason score of the recurrent cancer more than or equal to 9 are unlikely to be successfully salvaged. Patients failing initial hormonal therapy and radiation therapy are less likely to be successfully salvaged than patients failing radiation therapy only.

The aim of this study was to evaluate the prognostic role of several clinical variables in a patient population undergoing neoadjuvant hormonotherapy (NHT) with external beam radiotherapy (ERT) to identify subsets of patients with an unfavorable prognosis who require intensified therapy. Eighty-four patients (mean age, 68.2 +/– 6.1 years; range, 52–81 years) underwent ERT (45 Gy to pelvic volume; 65 Gy mean dose to prostate volume) and NHT (oral flutamide: 250 mg three times daily for 30 days; LH-RH analogue: one vial every 28 days starting two months before radiotherapy and for its entire duration). The distribution according to clinical stage was T2: 46.4%, T3: 50.0%, T4: 3.6%. The distribution according to the Gleason score was grade 2–4: 17.9%; grade 5–7: 53.6%; grade 8–10: 28.5%. The distribution according to pretreatment PSA levels (in ng/mL) was 0–4: 5.9%; 4–10: 26.2%; 10–20: 16.7%; ≥20: 51.2%. With a median follow-up of 36 months, 3.6% of patients died; hematogenous metastases and local disease progression were found in 16.7% and 6% of patients, respectively. Overall, the incidence of disease progression was 17.9%. 32.9% of patients showed biochemical failure during follow-up. Overall, metastasis-free, local progression-free and biochemical failure-free actuarial survival at five years was 89.2%, 66.5%, 85.0% and 41.9%, respectively. At univariate analysis (log-rank) clinical stage (cT) was shown to be significantly correlated with the incidence of metastasis (P = 0.0004), local progression (P <0.0001) and disease-free survival (P = 0.0005). At multivariate analysis (Cox) the correlations between clinical stage and metastasis (P = 0.0175), local progression (P = 0.0200) and disease-free survival (P = 0.0175) were confirmed. Gleason score and pretreatment PSA levels did not show any significant correlation with these endpoints. These results confirm the indications of the recent literature, which, in prostate carcinoma at higher clinical stages, suggest the use of prolonged hormonal therapy after radiotherapy.

Purpose Luminal breast cancer has a long natural history, with recurrences continuing beyond 10 years after diagnosis. We analyzed long-term follow-up (LTFU) of efficacy outcomes and adverse events in the Breast International Group (BIG) 1-98 study reported after a median follow-up of 12.6 years. Patients and Methods BIG 1-98 is a four-arm, phase III, double-blind, randomized trial comparing adjuvant letrozole versus tamoxifen (either treatment received for 5 years) and their sequences (2 years of one treatment plus 3 years of the other) for postmenopausal women with endocrine-responsive early breast cancer. When pharmaceutical company sponsorship ended at 8.4 years of median follow-up, academic partners initiated an observational, LTFU extension collecting annual data on survival, disease status, and adverse events. Information from Denmark was from the Danish Breast Cancer Cooperative Group Registry. Intention-to-treat analyses are reported. Results Of 8,010 enrolled patients, 4,433 were alive and not withdrawn at an LTFU participating center, and 3,833 (86%) had at least one LTFU report. For the monotherapy comparison of letrozole versus tamoxifen, we found a 9% relative reduction in the hazard of a disease-free survival event with letrozole (hazard ratio [HR], 0.91; 95% CI, 0.81 to 1.01). HRs for other efficacy end points were similar to those for disease-free survival. Efficacy of letrozole versus tamoxifen for contralateral breast cancer varied significantly over time (0- to 5-, 5- to 10-, and > 10-year HRs, 0.62, 0.47, and 1.35, respectively; treatment-by-time interaction P = .005), perhaps reflecting a longer carryover effect of tamoxifen. Reporting of specific long-term adverse events seemed more effective with national registry than with case-record reporting of clinical follow-up. Conclusion Efficacy end points continued to show trends favoring letrozole. Letrozole reduced contralateral breast cancer frequency in the first 10 years, but this reversed beyond 10 years. This study illustrates the value of extended follow-up in trials of luminal breast cancer.

PURPOSE: We conducted a phase II pilot study of dose-intensive adjuvant chemotherapy with doxorubicin followed sequentially by high-dose cyclophosphamide to determine the safety and feasibility of this dose-dense treatment and to estimate the disease-free and overall survival in breast cancer patients with four or more involved axillary lymph nodes. PATIENTS AND METHODS: Seventy-three patients received adjuvant treatment with four cycles of doxorubicin 75 mg/m2 as an intravenous bolus every 21 days, followed by three cycles of cyclophosphamide 3,000 mg/m2 every 14 days with granulocyte colony-stimulating factor support. RESULTS: Seventy-one patients were assessable, and all but two completed all planned chemotherapy. There was no treatment-related mortality. The most common toxicity was neutropenic fever, which occurred in 39% of patients. Median disease-free survival is 66 months (95% confidence interval, 34 to 98 months), and median overall survival has not yet been reached. At 5 years of follow-up, the disease-free survival is 51.7%, and overall survival is 60.0%. There is no long-term treatment-related toxicity, and no cases of acute myelogenous leukemia or myelodysplastic syndrome have been observed. CONCLUSION: Our pilot study of doxorubicin followed by cyclophosphamide demonstrates the safety and feasibility of the sequential dose-dense plan. Long-term follow-up, although noncomparative, is promising. However, this regimen is associated with a higher incidence of toxicity (and also higher costs) than the standard dose and schedule of doxorubicin and cyclophosphamide, and therefore it should not be used as conventional therapy in the absence of demonstrated improvement of outcome. Randomized trials testing the dose-dense approach have been completed but not yet reported. Because the sequential plan can decrease overlapping toxicities, it is an appropriate platform for the addition of newer active agents, such as taxanes or monoclonal antibodies.

Purpose The Cancer Research UK “Over 50s” trial compared 5 and 2 years of tamoxifen in women with early breast cancer. Results are reported after median follow-up of 10 years. Patients and Methods Between 1987 and 1997, 3,449 patients age 50 to 81 years with operable breast cancer who had been taking 20 mg of tamoxifen for 2 years were randomly assigned to either stop or continue for an additional 3 years, if they were alive and recurrence free. Data on recurrences, new tumors, deaths, and cardiovascular events were obtained (April 2010). Results There were 1,103 recurrences, 755 deaths as a result of breast cancer, 621 cardiovascular (CV) events, and 236 deaths as a result of CV events. Fifteen years after starting treatment, for every 100 women who received tamoxifen for 5 years, 5.8 fewer experienced recurrence, compared with those who received tamoxifen for 2 years. The risk of contralateral breast cancer was significantly reduced (hazard ratio, 0.70; 95% CI, 0.48 to 1.00). Among women age 50 to 59 years, there was a 35% reduction in CV events (P = .005) and 59% reduction in death as a result of a CV event (P = .02); in older women, the effect was much smaller and not statistically significant. Conclusion Taking tamoxifen for the recommended 5 years reduces the risk of recurrence or contralateral breast cancer 15 years after starting treatment. It also lowers the risk of CV disease and death as a result of a CV event, particularly among those age 50 to 59 years. Women should therefore be encouraged to complete the full course. Although aromatase inhibitors improve disease-free survival, tamoxifen remains a cheap and highly effective alternative, particularly in developing countries.

Abstract Introduction: FL is generally responsive to conventional-dose chemotherapy but long term disease-free survival (DFS) is uncommon. High-dose chemo-radiotherapy followed by ASCT has the potential to induce remission in this disease but the long-term benefit of this modality remains to be determined. Methods: Between 1990 and 2003, we transplanted 52 pts originally diagnosed with low-grade FL (31 grade 1, 21 grade 2). Twenty-five (48%) had biopsy-proven large cell transformation (FL grade 3 or diffuse large cell lymphoma) before ASCT. The median number of prior therapies was 2 (range: 1 to 7). Prior to ASCT, 45 pts (87%) were responsive to salvage therapy with 20 pts (38%) in CR. Five pts (10%) had chemo-resistant disease at the time of ASCT. High-dose regimens included BCNU-cyclophosphamide-etoposide (31%), melphalan/TBI (27%), and cyclophosphamide/TBI (25%). Thirty-eight pts (73%) received peripheral stem cells (PSCT) and 14 pts (27%) received autologous bone marrow (BM) with 4-hydroxyperoxycyclophosphamide (4-hc) purging in 9 cases (17%). The median age was 49 yrs (range: 29–65). Results: There was 1 treatment-related death during the first 100 days. After ASCT, 36 pts (69%) achieved a CR, 2 (4%) had a PR, and 7 (13%) had stable disease. Among those in CR, 20 (56%) had a CR pre-ASCT, 14 (41%) had a lesser response, and 1 (3%) was chemo-resistant. Median follow-up (f/u) of survivors was 5.3 yrs (range: 1.7 months to 12.4 yrs). The median overall survival (OS) has not yet been reached. The median event-free survival (EFS) is 3.4 yrs (range: 1.7 months to 12.4 yrs). Among complete responders, more than 50% are disease free at last follow-up (range 1.7 months to 12.1 yrs). Variables favorably affecting EFS and OS are age < 60 yrs (p = 0.007, 0.015 respectively), achievement of a CR after ASCT (p = 0.002, 0.001), absence of transformation (p = 0.038, 0.017), BM vs. PSCT (p = 0.042, 0.086), and 4-hc BM purging (p = 0.044, 0.059). Number of prior regimens, response prior to ASCT, type of preparative regimen, and addition of TBI, were not significantly associated with EFS, DFS, or OS. In multivariable analysis, achievement of CR after ASCT and age < 60 yrs are the only significant predictors of EFS and OS. Adjusted for age, 53% of pts with a CR after ASCT are alive and event-free at last f/u (range: 2.4 months to 12.4 yrs) (Figure 1). In contrast, the median EFS among pts without a CR is 0.5 yrs (range: 1.7 months to 5.3 yrs). Conclusion: ASCT is a reasonable therapeutic approach to FL, resulting in long term EFS for some pts, even with relapsed, refractory and/or transformed disease. In our experience, significant predictors of EFS and OS after ASCT are complete response and age <60. The appropriate application and timing of ASCT in the management of pts with FL needs to be further evaluated in randomized, controlled clinical trials. Figure Figure
