RESUMO

PURPOSES: Young breast cancer patients aged 35 years and younger are a small group of women who tend to present at high-risk form of the disease. More analysis of the data on tumor characteristics, treatment, and survival is necessary to help improving treatment and outcome. METHODS: In this retrospective study, we compared the clinical and tumor characteristics, the treatments, and the survival of 257 women aged ≤ 35 years, with 6566 women aged 50-69 years. We used a registry-based data of patients with invasive, non-metastatic breast cancer diagnosed between 2000 and 2015. RESULTS: Young women showed lower rate of hormone receptor (HR) positivity. Their tumors were more often HER2-positive, which showed lower rate of differentiation and higher rate of Ki-67 expression compared to their older counterparts. Women aged 35 years and younger were more likely to undergo neoadjuvant therapy and mastectomy. Endocrine therapy was underrepresented in young patients. 5-Year disease-free survival (DFS) was significantly lower in the younger patient group (81.7% vs. 91.3%, p < 0.001), while 5-year overall survival (OS) was not impaired (91.4% vs. 91.1%, p = 0.847). CONCLUSION: The unfavorable disease-free survival in the group of younger patients might be explained by their unfavorable tumor characteristics. The surgical treatment appears to be more aggressive in young breast cancer patients and is more frequently combined with chemotherapy and immunotherapy, either in a neoadjuvant or in an adjuvant setting.

RESUMO

OBJECTIVE: The aim of this study was to investigate the impact of pre-operative conization on disease-free survival (DFS) in early-stage cervical cancer. METHODS: In this population-based cohort study we analysed from clinical cancer registries to determine DFS of women with International Federation of Gynecology and Obstetrics (FIGO) stage IA1-IB1 cervical cancer with respect to conization preceding radical hysterectomy performed between January 2010 and December 2015. RESULTS: Out of 993 datasets available for the analysis, 235 patients met the inclusion criteria of the current study. The median follow-up was 5.4 years. During the study period, 28 (11.9%) recurrences were observed. All of these occurred in patients with FIGO stage IB1. For further evaluation, patients with FIGO IB1 tumors <2 cm were further analysed and divided into two groups, based on pre-operative conization. Pre-operative conization was associated with a reduced rate of recurrence (p = 0.007), with only three (5.2%) recurrences in this group (CO) compared to 25 recurrences (21.0%) in the group without conization (NCO) preceding radical hysterectomy. DFS was estimated at 79.0% and 94.8% in NCO and CO, respectively (p = 0.008). After adjustment for other prognostic covariates, conization remained a favourable prognostic factor for DFS (HR 0.27; 95% CI 0.08-0.93, p = 0.037). Lymph node involvement was the only unfavourable factor (HR 4.38; 95% CI 1.36-14.14, p = 0.014) in the multivariable analysis. CONCLUSIONS: Pre-operative conization is associated with improved DFS in early-stage cervical cancer independently of the surgical approach.

RESUMO

We investigated the survival effect of lymphadenectomy in ovarian cancer. The five-year progression-free and overall survival in early-stage ovarian cancer were not affected. Preliminary, unadjusted analysis in advanced ovarian cancer suggested an improvement in survival. However, after adjusting for other factors, e.g. ECOG performance status and patients' age, this survival advantage vanished. Our analysis suggests that systemic pelvic and para-aortic lymphadenectomy was not associated with an improvement of the progression-free and overall survival of patients with optimally debulked ovarian cancer.

RESUMO

INTRODUCTION: The G protein-coupled oestrogen receptor 1 (GPER-1) is a potential prognostic marker in breast cancer. However, its role in male breast cancer (MBC) is still unknown. This study evaluates the expression of GPER-1 in MBC samples and correlates these data with clinical and pathological parameters including patients' survival. MATERIAL AND METHODS: For this retrospective analysis of a prospectively maintained cohort of patients with MBC, we examined 161 specimens for GPER-1 expression using immunohistochemistry. An immunoreactive score (IRS) was calculated based on staining intensity and the percentage of positive tumour cells. Then, we correlated GPER-1 IRS with clinical and pathological parameters, and overall and relapse-free survival. RESULTS: About 40% of MBC samples were positive for GPER-1 expression (IRS ≥ 4). There was no significant correlation with clinicopathological parameters, such as hormone receptor status or grading. However, a statistical trend was observed for tumour size (≥ 2 cm, p = 0.093). Kaplan-Meier survival analysis revealed no significant correlation with relapse-free survival. However, there was a significant correlation with overall survival, but when we adjusted the log-rank p-value to compensate for the cut-off point optimization method, it rose above 0.1. Additionally, GPER-1-positive patients were older at diagnosis. When adjusted for age by multivariable Cox regression analysis, the significance of GPER-1 status for survival was further reduced. CONCLUSIONS: We found no significant prognostic value of GPER-1 in this MBC cohort as anticipated from studies on female BC. Future studies with higher sample size are needed to further verify a potential sex-specific role of GPER-1.

RESUMO

INTRODUCTION: The risk of contralateral lymph node metastases following unilateral sentinel lymph node (SLN) metastases in patients with vulvar cancer(s) remains to be systematically assessed. MATERIAL AND METHODS: We performed a multicenter, retrospective registry-based study of 476 patients with vulvar cancer. The primary outcome measure was the rate of contralateral non-SLN metastases in the case of positive unilateral SLN. RESULTS: Out of 476 patients with primary vulvar cancer, 202 received SLN biopsy: 58 unilateral and 144 bilateral. Out of 66 patients with unilateral metastatic SLN, 62 (93.9%) received contralateral lymphadenectomy-18 after unilateral and 44 after bilateral SLN biopsy. In the study group, 132 SLN were assessed with a median number of 2 (range 1-4) per patient and 76 of these were positive. Lymph node-positivity was associated with advanced tumor stage, as well as lymph and vascular space invasion. In the group of patients with bilateral inguino-femoral lymphadenectomy, 1004 lymph nodes were resected with a median number of 15 (range 10-29) per patient. After full dissection of the inguino-femoral lymph nodes, no contralateral non-SLN metastases were found. CONCLUSIONS: The risk of contralateral non-SLN metastases in patients with unilateral SLN metastases was low. Therefore, the impact of contralateral lymphadenectomy on patient survival should be investigated in further studies.

RESUMO

BACKGROUND: The axillary lymph node status is one of the most important prognostic factors in patients with early breast cancer. However, the impact of axillary lymph node micrometastases on survival remains unclear. There are no consistent recommendations for adjuvant chemotherapy (CHT). In this context, we aimed to investigate the impact of micrometastases on the clinical outcome of breast cancer patients according to the adjuvant CHT performed. PATIENTS AND METHODS: We conducted a retrospective population-based registry study of 26,465 patients aged between 24 and 97 years with primary breast cancer diagnosed between 2003 and 2017. Of these patients, 8856 with early breast cancer were eligible for analysis: 8316 (93.9%) were node negative and 540 (6.1%) had lymph node micrometastases. RESULTS: The median follow-up was 7.2 years, with a confidence interval (CI) of 7.1-7.3 years. Patients with lymph node micrometastases (pN1mi) without adjuvant CHT have reduced 10-year overall survival (OS) and recurrence-free survival (RFS) compared to patients who had axillary lymph node micrometastases and received an adjuvant CHT. However, this effect disappeared after adjustment for age, tumor size and tumor grading. Furthermore, in the group of patients with lymph node micrometastases, the administration of adjuvant CHT did not improve OS or RFS, compared to patients with lymph node micrometastases without adjuvant CHT: hazard ratio for treated patients was 1.51 (95% CI 0.80-2.85, p = 0.208) for OS and 1.12 (95% CI 0.63-1.97, p = 0.705) for RFS. CONCLUSION: Patients with axillary lymph node micrometastases showed a comparable outcome to node negative patients and their outcome was not significantly improved with CHT. Thus, axillary lymph node micrometastases should not be considered in the treatment decision.

RESUMO

PURPOSE: The aim of the study was to compare recurrence-free survival (RFS) and overall survival (OS) of patients with early stage cervical cancer in dependence of surgical approach and treatment center. PATIENTS AND METHODS: A population-based cohort study including women with early stage IA1-IIB2 cervical cancer treated by radical hysterectomy between January 2010 and December 2015 was performed. RESULTS: The median follow-up time was 5.6 years. After exclusions, 413 patients were eligible for analysis: 111 (26.9%) underwent minimal-invasive surgery (MIS) and 302 (73.1%) open surgery. Both treatment groups were well balanced regarding the clinical and pathological characteristics. The mean age of the patients was 51.0 years. MIS was associated with improved RFS and OS compared with the open surgery. The 5-year RFS rates were 89.2% in the MIS group and 73.4% in the open surgery group (p = 0.004). The 5-year OS rates were 93.7% in the MIS group and 81.8% in the open surgery group (p = 0.016). After adjustment for other prognostic covariates, the MIS was further associated with improved RFS (HR = 0.45, 95% CI 0.24-0.86; p = 0.015) but not with OS. Nevertheless, after adjustment for treatment center, the surgical approach was not associated with significant difference in RFS (HR = 0.61, 95% CI 0.31-1.19; p = 0.143). Overall survival of patients treated in university cancer centers was significantly increased compared to patients treated in non-university cancer centers. The treatment center remains a strong prognostic factor regarding RFS (HR = 0.49, 95% CI 0.28-0.83; p = 0.009) and OS (HR = 0.50, 95% CI 0.26-0.94; p = 0.031). CONCLUSIONS: The treatment center but not the surgical approach was associated with the survival of patients treated with radical hysterectomy for early stage cervical cancer.

RESUMO

BACKGROUND: Recently, sentinel lymph node mapping was introduced in the surgical staging of endometrial cancer as alternative to systematic lymphadenectomy. However, the survival impact of sentinel node mapping is not well characterized yet. METHODS: We performed retrospective study of 104 patients with endometrial cancer treated with sentinel lymph node alone (n = 52) or with pelvic and para-aortic lymphadenectomy (n = 52). For sentinel node mapping, indocyanine green was used. The outcome measure was disease-free survival. RESULTS: Median follow-up was 42 months. Fifty-two patients staged by sentinel lymph node mapping were matched in 1:1 ratio with 52 patients staged by lymphadenectomy using patient age, histological type, tumor stage, tumor grade and lymph and vascular space invasion as matching criteria. The median number of removed lymph node was 3 (range 1-6) and 36 (13-63) in the sentinel and lymphadenectomy group, respectively. The rate of lymph node metastases was not significantly higher in the sentinel group (19.2%) in comparison with the lymphadenectomy group (14.3%). The overall detection rate of sentinel lymph nodes was 100% with a bilateral mapping of 98.1%. Most of the 152 lymph nodes identified and removed were localized in upper paracervical pathway (n = 143, 94.1%). During the follow-up period, overall 21 (20.2%) events were observed, 8 (15.4%) in the sentinel group and 13 (25.0%) in the lymphadenectomy group. The estimated disease-free survival was 84.6% and 75.0% for patients in the sentinel and lymphadenectomy groups, respectively. The survival curves demonstrated similar disease-free survival in two groups (p = 0.774). CONCLUSION: Sentinel lymph node mapping did not compromise the outcome of patients with endometrial cancer.

RESUMO

BACKGROUND: The positive effect of systematic lymphadenectomy on survival of patients with endometrial cancer is a topic of ongoing debate. METHODS: We aimed to investigate whether systemic lymphadenectomy is beneficial for patients with early endometrial cancer. For this purpose, we analyzed a population-based registry with of 2392 women with endometrioid endometrial cancer, stage I and II at intermediate and high risk of recurrence. The primary outcome measure was overall survival. RESULTS: After exclusions, 868 women were eligible for analysis. Of those, 511 and 357 were categorized as intermediate (pT1A G3 and pT1B G1-2) and high risk (pT1B G3 and pT2 G1-3) early stage endometrial cancer, respectively. Lymphadenectomy was performed in 527 (60.7%) of the cases. Patients in the lymphadenectomy group were significantly younger, presented with more tumors of intermediate or undifferentiated grade and exhibited significantly lower co-morbidity rates and Eastern Cooperative of Oncology Group (ECOG) performance status. Median follow-up was 6.7 years. Recurrence-free survival was not improved by lymphadenectomy in the intermediate and high-risk group of patients. During the follow-up period, 111 (12.8%) women had disease recurrence and 302 (34.8%) died. Systematic lymphadenectomy was associated with significant improvement of overall survival in the pT1A G3 and pT1B G3 patient subgroups. Notably, adjustment for patient age and ECOG status abolished the improvement of overall survival by systematic lymphadenectomy in all groups. Thus, lymphadenectomy did not improve recurrence-free survival in the intermediate risk or the high-risk group of patients CONCLUSIONS: Systematic pelvic and para-aortic lymphadenectomy did not improve the survival of patients with early stage I and II endometrioid endometrial cancer at intermediate and high risk of recurrence.

RESUMO

BACKGROUND: Due to the lack of prospective data, current treatment of male breast cancer (MBC) is based on information obtained from retrospective analysis or by extrapolation from studies on female patients. In this prospectively enrolled cohort study, we retrospectively examined the survival effect of tamoxifen in MBC patients. METHODS: In this prospectively enrolled cohort study, 448 patients with MBC were treated between May 2009 and June 2018. The primary endpoint was disease-free survival (DFS). RESULTS: Between May 2009 and June 2018, 448 men with breast cancer were identified, with a median age at diagnosis of 69 years (range 27-96 years). The median follow-up was 39 months (range 3-89 months). Most tumours were larger than 20 mm; invasive ductal carcinoma was of no special histological type and with an intermediate grade of differentiation. Almost half of the men were diagnosed with positive axillary lymph nodes (43.5%). Hormone receptor (HR) positivity was observed in 98.4% of the patients. Notably, DFS among men who did not receive tamoxifen was significantly reduced as compared with those who underwent tamoxifen therapy (P = 0.002). The recurrence rate and mortality in the group of patients without and with tamoxifen treatment were 18.2% and 11.2%, respectively. The most common localisation of metastases was the bone. After adjustment for prognostic factors, we found that tamoxifen was found to reduce the recurrence rate by 68% (hazard ratio HR = 0.32; 95% confidence interval, CI: 0.14-0.74). CONCLUSIONS: Tamoxifen treatment was associated with improved DFS for MBC patients. CLINICAL TRIAL REGISTRATION: DRKS00009536.

RESUMO

BACKGROUND: The relationship between nodal micrometastases and clinical outcome of endometrial cancer is unclear. PATIENTS AND METHODS: We performed a multicenter, retrospective registry-based study of 2392 patients with endometrial cancer with and without nodal micrometastases. The primary outcome measure was disease-free survival. RESULTS: After exclusions, the final study involved 428 patients: 302 (70.6%) with node-negative endometrial cancer, who did not receive adjuvant treatment, 95 (22.2%) with nodal micrometastases who received adjuvant treatment, and 31 (7.2%) with nodal micrometastases who did not receive adjuvant treatment. The median follow-up was 84.8 months. Without adjuvant therapy the disease-free survival in the cohort of patients with micrometastases was significantly reduced as compared with disease-free survival in the node-negative cohort (p = 0.0001). With adjuvant therapy the median disease-free survival of patients with nodal micrometastases was similar with those of node-negative patients (p = 0.648). The adjusted hazard ratio for disease events among patients with micrometastases and no adjuvant therapy, as compared with node-negative patients, was 2.23 (95% confidence interval [CI] 1.26-3.95). In the cohort with micrometastases the relative risk of events was significantly decreased by adjuvant therapy (HR 0.29, 95%CI 0.13-0.65) even after adjustment for age at diagnosis, myometrial invasion, histological grade and type, and performance status. CONCLUSIONS: Nodal micrometastases are associated with decreased disease-free survival of patients with endometrial cancer. Adjuvant therapy was associated with improved disease-free survival of patients with micrometastases.

RESUMO

PURPOSE: HER2 expression has been reported to be discordant between primary tumor and metastatic tissue. PATIENTS AND METHODS: HER2 discordance and relation to HER2-targeted treatment was investigated in 227 patients with primary breast cancer. RESULTS: HER2 discordance between primary biopsy and second biopsy after neoadjuvant or adjuvant treatment was observed in 20.7%. This discordance was related only to the use of HER2-targeted treatment: 30 of 33 (90.9%) women with downgraded HER2 expression underwent a HER2-targeted therapy, whereas in the group of patients with concordant HER2 expression, only 32 of 180 (17.8%) received HER2-targeted treatment (p < 0.0001). HER2 discordance was associated with reduced disease-free survival but not overall survival. In a second cohort, including patients with HER2 overexpressing tumors, trastuzumab treatment was associated with change of HER2 expression from positive to negative in 47.3% of cases. Addition of pertuzumab increased the rate of HER2 loss up to 63.2%. Notably, the interval between last HER2-targeted treatment and the time of surgical excision of the tumor after neoadjuvant chemotherapy (NACT) or the biopsy of the metachronous metastasis was associated with a significant change in HER2 expression. The median time between NACT and the time of surgical excision was 23 days (range 5-81 days) for tumors with decreased HER2 expression and 51 days (range 10-179 days) for tumors with concordant HER2 expression. Furthermore, median time between the end of adjuvant treatment and second histology of the metachronous metastases accounted for 15 days (range 2-165 days) and 478 days (range 7-2739 days) was observed in the group of patients with decreased or unchanged HER2 expression, respectively. CONCLUSION: The interval between anti-HER2 treatment and the determination of HER2 in second histology is strongly associated with HER2 expression.

RESUMO

PURPOSE: Thromboembolism is a common adverse event in women treated with tamoxifen (TAM) for breast cancer. The risk in male breast cancer patients is poorly investigated. We aimed to examine the risk of thrombotic events after TAM in male breast cancer patients. PATIENTS AND METHODS: In this prospective cohort study, 448 patients treated between May 2009 and July 2017 for male breast cancer (BC) were assessed for eligibility. Patients with follow-up shorter than 6 months were excluded. The cumulative risk of thromboembolism was evaluated. RESULTS: The median follow-up was 47 months (range 6-101 months) with a median age of 69.4 years (range 27-89 years). Oestrogen receptor and progesterone receptor expression levels were observed in 98.3 and 94.9% of cases, respectively. During the follow-up period, thrombotic events were documented in 21 (11.9%) of 177 patients receiving TAM and in 1 (2.5%) of 41 patients who did not receive tamoxifen. The estimated incidence was 51.9 per 1000 person-years and 21.5 per 1000 person-years, respectively. Notably, the highest risk was identified in the first 18 months, where 81% of the observed thrombotic events occurred. Patients aged older than 71 years had a significantly increased risk of thrombotic event under TAM treatment than their younger counterparts (p = 0.033). History of thrombotic event, cardiovascular and liver disease, as well as additional adjuvant treatment were not associated with increased thrombotic risk. CONCLUSION: The risk of thrombotic event in men treated with TAM for breast cancer is markedly increased in the first 18 months of treatment, and should be considered during treatment decisions.

RESUMO

PURPOSE: To evaluate the pattern of endometrial cancer recurrence according to its biological subtype in a large cohort of patients. PATIENTS AND METHODS: Patients were stage eligible if they had a description of registry risk of recurrence status and were not primary metastatic. Data were prospectively collected. The primary endpoints were the subtype-dependent pattern and time of recurrence. RESULTS: The median follow-up time was 84 months. The highest 10-year recurrence-free and overall survival were seen in the group of patients at low risk of recurrence, 83.1 and 94.1%, respectively. The 10-year recurrence-free survival for intermediate and high risk group was 65.7 and 56.2%, respectively, whereas the estimated 10-year overall survival for both groups was 84.5 and 79.3%, respectively. Patients at high risk demonstrated the highest levels of disease recurrence in the first 3-4 years after diagnosis and the most common site of metastasis was the lung. In contrast, the rate of recurrence for patients at intermediate and low risk of recurrence in the first 5 years was relatively low but remained continuous up to 10 years of follow-up. Overall, the most common site of relapse was local recurrence. CONCLUSION: Endometrial cancer subtypes are associated with different times and patterns of recurrence and this should be considered when determining the treatment strategy.

RESUMO

BACKGROUND: There is limited information about survival effect of vaginal brachytherapy (VBT) and its comparison to external beam pelvic radiotherapy (EBRT) and no radiotherapy (no-RT) of endometrial cancer patients. PATIENTS AND METHODS: We performed a multicenter retrospective registry study of 1550 patients with endometrial cancer treated by no-RT (n = 702), VBT (n = 430) and EBRT ± VBT (n = 418). The outcome measure was overall survival. RESULTS: RT did not improve the overall survival of patients with a low risk of recurrence. In univariate analysis, the survival effect of VBT was significant in patients with intermediate and high risk of recurrence (HR 0.42, CI 0.29-0.60, p < 0.0001). EBRT ± VBT demonstrated no survival effect in these groups. Multivariate analysis showed that VBT (HR 0.50, CI 0.36-0.71) significantly reduced the mortality risk in patients with an intermediate and high risk compared with no-RT after adjustment for age, tumor grading, tumor stage, lymphadenectomy, adjuvant therapy and comorbidities. Matching for age, histological type, tumor stage, tumor grade, and performance status between patients treated with no-RT and VBT was performed. The matching analysis again demonstrated the favorable survival effect of VBT compared to no-RT on overall survival with an absolute risk reduction of 17.7%. Notably, in a further 106 matched pairs, EBRT ± VBT did not demonstrate any survival effect over VBT among patients at intermediate and high risk of recurrence. CONCLUSIONS: VBT should be performed in patients at intermediate and high risk of recurrence of endometrial cancer, after operative determination of lymph node status.

RESUMO

PURPOSE: To evaluate the pattern of recurrence of breast cancer according to its biological subtype in a large cohort of patients treated with therapy representative of current practice. PATIENTS AND METHODS: Patients treated between 2000 and 2016 with known biological subtype were eligible. Data were prospectively collected. Primary endpoint was the subtype-dependent pattern and time of recurrence. Loco-regional and distant site and time of recurrence were assessed. RESULTS: Median follow-up time was 80.8 months. For 12,053 (82.5%) of 14,595 patients with primary non-metastatic invasive breast cancer a subtype classification was possible. The luminal A subtype had the highest 10-year survival followed by luminal B and luminal/HER2. The worst survival demonstrated HER2 enriched and TNBC. HER2 and TNBC had the highest rate of recurrence in the first 5 years, whereas the rate of recurrence for luminal A and luminal B tumors was initially low, but remained continuously even after 10 years of follow-up. Luminal A tumors demonstrated the lowest rate of distant metastases predominantly in bone. So did luminal B tumors. HER2 enriched subtype was characterized with increased rate of loco-regional recurrence and distant metastases in bone, liver and brain. Luminal/HER2 had pattern of relapse similar to HER2 enriched tumors, with exception of loco-regional relapse and brain metastases. TNBC had higher rate of lung, bone and brain metastases as well as loco-regional relapse. CONCLUSION: Breast cancer subtypes are associated with different time and pattern of recurrence and it should be considered during treatment decision.

RESUMO

BACKGROUND: Oophorectomy is generally performed in patients with endometrial cancer despite the rate of ovarian metastasis being relatively low. PATIENTS AND METHODS: A multicenter retrospective registry-based study was performed in 2329 patients with endometrial cancer. The outcome measures were the incidence of ovarian metastasis and the impact on overall survival. RESULTS: Median follow-up was performed at 84 months. A total of 2158 women were eligible for analysis, of which 131 (6.1%) had ovarian metastasis. Women with ovarian metastasis were more likely to have > 50% myometrial invasion, undifferentiated nonendometrioid tumors, and lymph and vascular space invasion. The presence of < 50% myometrial invasion, endometrioid histology, well-differentiated cancer, and negative lymph and vascular space invasion were associated with a very low rate (0.5%) of ovarian metastasis. Notably, after matching for tumor histology and grade, myometrial invasion, and lymph and vascular space invasion, ovarian metastasis was not associated with a reduced median overall survival. CONCLUSIONS: Ovarian preservation should be offered to premenopausal women with endometrial cancer in whom myometrial invasion is less than 50%, the histological type is endometrioid and well-differentiated, and lymph and vascular space invasion is not involved.

RESUMO

BACKGROUND: Elderly women with cervical cancer receive less therapy in comparison with their younger counterparts. The exact reason(s) for this treatment strategy remains unclear. PATIENTS AND METHODS: We performed a multicenter, retrospective registry-based study of 1559 patients with cervical cancer. The primary outcome was the reason for not performing the indicated treatment. RESULTS: Median follow-up was 67.8 months. A total of 956 women were eligible for analysis: 693 (64.2%) were younger than 60 years and 387 (35.8%) were aged 61 years old and older. Elderly women were more likely to have undifferentiated cervical cancer at an advanced stage. For early stage (stage IA1-IIA), tumors patients 61 years old and older were less likely to receive surgery [odds ratio (OR) 0.39; 95% CI 0.20-0.77] and radiochemotherapy (OR 0.37; 95% CI 0.21-0.66) compared with the group of patients aged < 60 years. The rate of lymphadenectomy was similar in both age groups. Patients 61 years old and older with advanced stage (IIB-IV) cervical cancer were also less likely to receive surgery [odds ratio (OR) 0.42; 95% CI 0.27-0.66], lymphadenectomy (OR 0.30; 95% CI 0.12-0.51) and radiochemotherapy (OR 0.31; 95% CI 0.20-0.48) compared with patients aged < 60 years. Notably, the rate of indicated but not performed therapies proportionally increased with an increase in patient age and the most important reason for this phenomenon was the failing of recommendation. CONCLUSIONS: Elderly women with cervical cancer are undertreated and this is more likely because the therapy was not recommended.

RESUMO

Purpose The GeparQuinto phase III trial demonstrated a lower pathologic complete response (pCR; pT0 ypN0) rate when lapatinib was added to standard anthracycline-taxane chemotherapy compared with trastuzumab in patients with human epidermal growth factor receptor 2 (HER2) -positive breast cancer. Here, we report the long-term outcomes. Methods Patients with HER2-positive tumors (n = 615) received neoadjuvant treatment with epirubicin (E) plus cyclophosphamide (C), followed by docetaxel (T) in combination with either lapatinib (L) or trastuzumab (H; ECH-TH arm: n = 307; ECL-TL arm: n = 308). All patients received adjuvant trastuzumab for a total of 12 months and 18 months in the ECH-TH and ECL-TL arms, respectively. Median follow-up was 55 months. Results Three-year disease-free survival (DFS), distant DFS (DDFS), and overall survival (OS) were not significantly different between the two treatment arms. Long-term outcomes correlated with pCR (DFS: hazard ratio [HR], 0.63; P = .042; DDFS: HR, 0.55; P = .021; and OS: HR, 0.31; P = .004). A benefit only for OS was observed in patients who were treated with trastuzumab and achieved pCR versus no pCR (HR, 0.15; P = .010), whereas no difference was found in patients with pCR versus without pCR in the lapatinib arm. DFS and DDFS remained unchanged in both treatment arms according to hormone receptor status, whereas OS was significantly better in hormone receptor-positive patients who were treated with neoadjuvant lapatinib (HR, 0.32; P = .019), followed by adjuvant trastuzumab. No difference was observed in hormone receptor-negative patients; however, the small number of events limits this interpretation. Within the hormone receptor-negative cohort, pCR was significantly associated with DFS, DDFS, and OS ( P = .002, .005, and .002, respectively). Conclusion pCR correlated with long-term outcome. In patients with hormone receptor-positive tumors, prolonged anti-HER2 treatment-neoadjuvant lapatinib for 6 months, followed by adjuvant trastuzumab for 12 months-significantly improved survival compared with anti-HER2 treatment with trastuzumab alone.

RESUMO

PURPOSE: Precise presurgical diagnosis of tumour size is essential for adequate treatment of male breast cancer (MBC). This study is aimed to compare the accuracy of clinical measurement (CE), ultrasound (US) and mammography (MG) for preoperative estimation of tumour size. METHODS: This study was conducted as a prospective, multicentre register study. One hundred and twenty-nine male patients with invasive breast cancer were included. CE, US and MG were performed in 107, 110 and 75 patients, respectively, and the estimated tumour size was compared with the histopathological (HP) tumour size. RESULTS: All methods tended to underestimate the HP tumour size. None of the methods were significantly more accurate than the others in determining the maximal tumour diameter. The sensitivity within 5 mm tolerance for US was 65.5%, which was better than for MG (61.3%) and CE (56.6%). In the group of patients with pT2 tumours, MG showed significantly better accuracy than US. The measurements obtained with each method were significantly correlated with the HP measurements. The highest correlation coefficient was observed for MG (0.788), followed by US (0.741) and CE (0.671). CONCLUSIONS: Our data demonstrate that MG and US have similar accuracy with regard to tumour size estimation. US assessment showed the highest sensitivity in determining tumour size, followed by MG and CE. However, MG demonstrated a significant advantage for estimating the real tumour size for pT2 tumours compared to US or CE.
