Total pathological complete response versus breast pathological complete response in clinical trials of reference and biosimilar trastuzumab in the neoadjuvant treatment of breast cancer

Introduction: Trastuzumab is a key drug in the neoadjuvant treatment of breast cancers that overexpress the human epidermal growth factor receptor 2 (HER2). Pathological complete response (pCR) is commonly used as an endpoint in neoadjuvant clinical trials of trastuzumab as evidence suggests it may be a surrogate for long-term survival. Several biosimilar candidates of originator or ‘reference’ trastuzumab are in development and have used pCR as a primary endpoint to assess therapeutic equivalence between treatments. The exact definition of pCR has varied across studies.

Areas covered: Here we look at the clinical relevance of pCR and compare rates of total pCR (defined as ypT0/is ypN0) and breast pCR (defined as ypT0/is) in clinical trials of reference and biosimilar trastuzumab.

Expert commentary: In order to evaluate the efficacy of neoadjuvant systemic therapies in a uniform way, standardization of trial endpoints is necessary. Future studies in HER2-positive breast cancer should include full assessment of the breast and lymph node basin before and after neoadjuvant systemic therapy, and the use of total pCR as the primary outcome.

Explaining the difference in prognosis between screen-detected and symptomatic breast cancers

Background:

We analysed 10-year survival data in 19 411 women aged 50–64 years diagnosed with invasive breast cancer in the West Midlands region of the United Kingdom. The aim was to estimate the survival advantage seen in cases that were screen detected compared with those diagnosed symptomatically and attribute this to shifts in prognostic variables or survival differences specific to prognostic categories.

Methods:

We studied tumour size, histological grade and the Nottingham Prognostic Index in very narrow categories and investigated the distribution of these prognostic factors within screen-detected and symptomatic tumours. We also adjusted for lead time bias.

Results:

The unadjusted 10-year breast cancer survival in screen-detected cases was 85.5% and in symptomatic cases 62.8% after adjustment for lead time bias, survival in the screen-detected cases was 79.3%. Within narrow categories of prognostic variables, survival differences were small, indicating that the majority of the survival advantage of screen detection is due to differences in the distributions of size and node status.

Conclusion:

Our results suggested that a combination of lead time with size and node status in 10 categories explained almost all (97%) of the survival advantage. Only a small proportion remained to be explained by biological differences, manifested as length bias or overdiagnosis.     

Molecular characteristics of screen-detected vs symptomatic breast cancers and their impact on survival

Background:

Several recent studies have shown that screen detection remains an independent prognostic factor after adjusting for disease stage at presentation. This study compares the molecular characteristics of screen-detected with symptomatic breast cancers to identify if differences in tumour biology may explain some of the survival benefit conferred by screen detection.

Methods:

A total of 1379 women (aged 50–70 years) with invasive breast cancer from a large population-based case–control study were included in the analysis. Individual patient data included tumour size, grade, lymph node status, adjuvant therapy, mammographic screening status and mortality. Immunohistochemistry was performed on tumour samples using 11 primary antibodies to define five molecular subtypes. The effect of screen detection compared with symptomatic diagnosis on survival was estimated after adjustment for grade, nodal status, Nottingham Prognostic Index (NPI) and the molecular markers.

Results:

Fifty-six per cent of the survival benefit associated with screen-detected breast cancer was accounted for by a shift in the NPI, a further 3–10% was explained by the biological variables and more than 30% of the effect remained unexplained.

Conclusion:

Currently known biomarkers remain limited in their ability to explain the heterogeneity of breast cancer fully. A more complete understanding of the biological profile of breast tumours will be necessary to assess the true impact of tumour biology on the improvement in survival seen with screen detection.     

Second breast cancers in a Tuscan case series: characteristics, prognosis, and predictors of survival

Little is known about long-term outcomes following a second breast cancer diagnosis. We describe the epidemiology, characteristics and prognosis of second breast cancers in an Italian cohort. We identified women with two breast cancer diagnoses from 24 278 histology records at a Tuscan breast cancer service between 1980 and 2005, and determined their survival status. Disease-specific survival from second diagnosis was examined using Cox regression analyses. Second cancers were identified in 1044 women with a median age of 60 years. In all 455 were ipsilateral relapses and 589 were contralateral cancers. Median time between first and second diagnosis was 63.4 months. The majority of second cancers was small invasive or in situ tumours. Estimated 10-year survival from a second cancer diagnosis was 78%. Survival was poorest when the second cancer was large (HR=2.26) or node-positive (HR=3.43), when the time between the two diagnoses was <5 years (HR=1.45), or when the diagnosis was in an earlier epoch (HR=2.20). Second tumours were more likely to be large or node-positive if the first breast cancer had these features. Prognosis following a second breast cancer in this cohort was generally good. However, large or node-positive second tumours, and shorter intervals between diagnoses were indicators of poorer survival.

Tumor parameters, clinical and pathological responses, medical management, and survival through time on 710 operable breast cancers

The aim of the current study is an analysis of tumor parameters, clinical and pathological responses, medical management, and survival on 710 operable breast cancer patients who received neoadjuvant chemotherapy from 1982 to 2004 and were grouped into four successive periods according to diagnosis date: (1) 1982–1989; (2) 1990–1994; (3) 1995–1999; and (4) 2000–2004. Patients were treated by different neoadjuvant chemotherapies combinations : AVCF/M, TNCF, NEM, NET, TAXOTERE, FEC 50, 75, 100, FAC 50, and TAXOTERE-TNCF, mainly in successive prospective phase II trials. They received a median number of six cycles (range, 1–9). After primary chemotherapy, patients underwent a surgery and a radiotherapy. In case of significant residual disease, some patients received additional courses of chemotherapy. In addition, menopausal patients with hormonal receptor-positive tumors received tamoxifen for 5 yr. Clinical factors had some remarkable variations with time. The median age of the patients was 49.5 yr (range, 26–81). The size of the tumor was significantly greater from 1995; conversely, clinical lymph-node involvement was lower in period 4 than in the first period. The percentage of invasive ductal carcinoma and of SBR III tumors increased about 20% from 1982–1989 to 2000–2004. The number of positive hormonal receptors increased from 38.3% in period 1 to 74% in period 4. The clinical response rate improved recently from before 1990. The pathological response rate was greater in periods 2 and 3 than in periods 1 and 4. An adjuvant hormonotherapy became progressively more frequently given (44.7 for period 1 and 73.3% for period 4). Finally, no significant difference was found when we compared overall and disease-free survival through the four periods. It appears that the progressive increase of tumor burden was compensated by more effective treatments.     

Prognostic characteristics in breast cancers after hormone replacement therapy

Summary We examined the influence of hormone replacement therapy (HRT) on breast tumour biology by comparing the prognostic characteristics of breast cancers and survival in 121 women prescribed replacement hormones before diagnosis with those in 1468 women without such treatment. The women receiving HRT had a lowered relative risk of being diagnosed with tumours of more than 20 mm in diameter, OR = 0.7 (CI 0.5–1.0) and axillary lymph node dissemination, OR = 0.7 (CI 0.4–1.1). These risk reductions were most pronounced and statistically significant in the women who had been prescribed a combined estradiol-progestin regimen. The patients in this compound group also had a diminished relative risk of having poorly differentiated tumours. Further, there was an indication that the women prescribed HRT, and especially those with conjugated estrogens/estradiols alone, had a decreased relative risk of developing aneuploid tumours. There was no clear pattern for women receiving the biologically weak oestriol, although risk estimates were generally higher for unfavourable tumours in comparison with those receiving the higher potency compounds. Adjustments for indications of earlier detection (i.e. lead time bias) did not influence the pattern or magnitude of the risk estimates. No association between any type of HRT and survival after breast cancer diagnosis was noted, but analyses were based only on 19 breast cancer deaths among exposed patients. We conclude that breast cancers occurring after treatment with HRT, especially the combined estrogen-progestin regimen, seem to have more favourable tumour features than tumours in non-treated women. Our findings may reflect a less aggressive biological behaviour of breast cancers in women receiving HRT, or in part be explained by the earlier detection of the tumours in these women.

Radiological staging in breast cancer: which asymptomatic patients to image and how

Background:

Approximately 4% of patients diagnosed with early breast cancer have occult metastases at presentation. Current national and international guidelines lack consensus on whom to image and how.

Methods:

We assessed practice in baseline radiological staging against local guidelines for asymptomatic newly diagnosed breast cancer patients presenting to the Cambridge Breast Unit over a 9-year period.

Results:

A total of 2612 patients were eligible for analysis; 91.7% were appropriately investigated. However in the subset of lymph node negative stage II patients, only 269 out of 354 (76.0%) investigations were appropriate. No patients with stage 0 or I disease had metastases; only two patients (0.3%) with stage II and ⩽3 positive lymph nodes had metastases. Conversely, 2.2, 2.6 and 3.8% of these groups had false-positive results. The incidence of occult metastases increased by stage, being present in 6, 13.9 and 57% of patients with stage II (⩾4 positive lymph nodes), III and IV disease, respectively.

Conclusion:

These results prompted us to propose new local guidelines for staging asymptomatic breast cancer patients: only clinical stage III or IV patients require baseline investigation. The high specificity and convenience of computed tomography (chest, abdomen and pelvis) led us to recommend this as the investigation of choice in breast cancer patients requiring radiological staging.

CORRELATION OF STEROID HORMONE RECEPTORS AND CLINICAL PATHOLOGICAL FEATURES WITH PROGNOSIS OF HUMAN BREAST CANCER

Clinical, pathological features and steroid hormone receptors (SR) including receptors of estrogen (ER), progesterone (PR) and androgen (AR) were observed in 58 cases of breast carcinoma, and related to patient 5- year survival rate through stratification and multivariatc analysis. The results showed that histologic tumor type and grading, lymphnode status, ER value and patient age took more important role in patient survival, and SR, especially, conferred survival advantage in advanced cases with tumor size larger than 2 cm, node involved, or TNM Stage Ⅱ-Ⅲ.     

Histoculture of human breast cancers

Breast cancers from 53 patients were explanted in culture, and 39 with two-year or more follow-up and documentable tissue forms of cancer in culture (histoculture) are the subject of this report. Clinicopathologic findings have been correlated with dynamic aspects of the cancers in short-term histocultures, including cell cohesiveness, yield and survival time of the cancer cells in culture, emigration of macrophages from the explants, and the occurrence of special interactions of lymphocytes with cancer cells. The outstanding finding was the association of special lymphocyte-cancer cell interactions with a more favorable prognosis; six of seven patients (86%) with infiltrating ductal cancer showing lymphocyte congregation, emperiopolesis, or other special activity were tumor-free survivors. Additional findings were: 1) patients having four or fewer lymph nodes positive for cancer had a survival rate of 50%, but this fell to 20% when emigrating macrophages were not present in the cancer cultures; 2) eight of the 12 patients (67%) having discoid histoculture survival time of less than one week were tumor-free, as opposed to three of eight patients (27%) where tumor survival in vitro was greater than one week. The reverse was true for nondiscoid, poorly cohesive colonies of cancer; 3) the combination of tumor-negative lymph nodes and low in vitro cancer yield was associated with the best patient survival rate, 64%. However, the combination of negative nodes and high in vitro yield was linked to the worst patient survival (20%). Although the overall study does not permit definitive conclusions, there is an undeniable potential for the use of histocultures in the evaluation of human cancers. Expanded studies are warranted, including larger numbers of tumors and cultures, and longer patient follow-up periods.     

乳腺浸润性微乳头状癌临床病理特征及预后分析

目的 乳腺浸润性微乳头状癌(invasive micropapillary carcinoma,IMPC)是一种特殊类型的乳腺浸润性癌,易发生淋巴管、血管侵犯,但对其预后的认识仍存在分歧.本研究拟探讨IMPC的临床病理特征及预后相关性,为临床治疗提供指导.方法 采用回顾性分析的方法,形态学观察并评估2006-06-19-2015-10-28国家癌症中心中国医学科学院肿瘤医院病理确诊的89例乳腺IMPC中微乳头状结构的比例,应用免疫组化方法检测ER、PR、HER2及Ki-67的表达,并对各临床病理因素进行生存分析.结果 肿瘤内微乳头状癌比例>50%组ER阳性率为85.7%,高于微乳头状癌比例25%~50%组(57.1%)和<25%组(40%),P=0.013;单纯性IMPC组伴脉管瘤栓比率为58.8%,高于混合性IMPC组的32.4%,P=0.018.随访资料显示,微乳头状癌比例>50%组复发/转移率为9.1%,低于微乳头状癌比例25%~50%组(28.6%)和<25%组(40.0%),P=0.047.Kaplan-Meier单因素生存分析显示,微乳头状癌成分>50%组无瘤生存期长于微乳头状癌成分25%~50%组与<25%组,χ2=4.296,P=0.038;ER阳性组无瘤生存期长于ER阴性组,χ2=5.324,P=0.021;原发肿瘤T1组无瘤生存期长于T2组,χ2=7.302,P=0.026.Cox多因素生存分析未发现,影响乳腺IMPC无瘤生存时间的独立预后因素.结论 乳腺IMPC虽然易于发生脉管侵犯,但其侵袭性、转移能力及恶性度并不因而增高;原发肿瘤大小、ER状态、微乳头癌比例可能与其预后相关,但有待扩大样本及更长期随访数据的支持.

Bone marrow micrometastases in 109 breast cancer patients: Correlations with clinical and pathological features and prognosis

Background: The presence in bone marrow of cells which react with monoclonal antibodies against tumor-associated antigens has been proposed over the last few years as a new prognostic factor in breast cancer patients. Patients and methods: Bone marrow aspirates were obtained from 109 stage I and II breast cancer patients during or 2–4 weeks after primary surgery. The samples were processed for leukocyte separation on a Ficoll-Hypaque gradient and then used to prepare cytospin slides for immunocytochemical analysis. The slides were stained with a pool of monoclonal antibodies (MoAbs) which recognize tumor associated antigens, using the alkaline phosphatase anti-alkaline phosphatase method. The median follow-up was 36 months (range 15–62); 22 patients relapsed and 7 died. Results: Thirty-four of the 109 patients (31.1%) had MoAb positive bone marrow cells. The bone marrow was positive in 28/74 (37.9%) patients who had the aspirate taken during surgery and in 6/35 (17.1%) who had it taken after surgery (p = 0.055). No association was found between bone marrow positivity and tumour size, nodal status, menopausal status, estrogen receptor positivity or the proliferative index. No association was found between bone marrow and prognosis: the log-rank test was 0.291 (p > 0.5) for OS and 0.023 for DFS; the hazard ratio (positive vs negative) was 1.51 for OS (95% CI: 0.33–6.86) and 0.93 for DFS (95% CI: 0.35–2.45). Conclusions: In our series, bone marrow positivity did not correlate with prognostic parameters or prognosis. Of interest is the relative excess of positivity when the bone marrow was obtained during surgery.
