Hoffmann J, Wallwiener D. Classifying breast cancer surgery: a novel, complexity-based system for oncological, oncoplastic and reconstructive procedures, and proof of principle by analysis of 1225 operations in 1166 patients. BMC Cancer 2009; 9:108. [PMID: 19356240 PMCID: PMC2679762 DOI: 10.1186/1471-2407-9-108] [Citation(s) in RCA: 41] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2008] [Accepted: 04/08/2009] [Indexed: 11/17/2022] Open
Abstract
Background One of the basic prerequisites for generating evidence-based data is the availability of classification systems. Attempts to date to classify breast cancer operations have focussed on specific problems, e.g. the avoidance of secondary corrective surgery for surgical defects, rather than taking a generic approach. Methods Starting from an existing, simpler empirical scheme based on the complexity of breast surgical procedures, which was used in-house primarily in operative report-writing, a novel classification of ablative and breast-conserving procedures initially needed to be developed and elaborated systematically. To obtain proof of principle, a prospectively planned analysis of patient records for all major breast cancer-related operations performed at our breast centre in 2005 and 2006 was conducted using the new classification. Data were analysed using basic descriptive statistics such as frequency tables. Results A novel two-type, six-tier classification system comprising 12 main categories, 13 subcategories and 39 sub-subcategories of oncological, oncoplastic and reconstructive breast cancer-related surgery was successfully developed. Our system permitted unequivocal classification, without exception, of all 1225 procedures performed in 1166 breast cancer patients in 2005 and 2006. Conclusion Breast cancer-related surgical procedures can be generically classified according to their surgical complexity. Analysis of all major procedures performed at our breast centre during the study period provides proof of principle for this novel classification system. We envisage various applications for this classification, including uses in randomised clinical trials, guideline development, specialist surgical training, continuing professional development as well as quality of care and public health research.

Abstract
PURPOSE To compare the efficacy of neoadjuvant (NA) docetaxel (DOC) with anthracycline-based therapy and determine the efficacy of NA DOC in patients with breast cancer initially failing to respond to anthracycline-based NA chemotherapy (CT). PATIENTS AND METHODS Patients with large or locally advanced breast cancer received four pulses of cyclophosphamide 1,000 mg/m(2), doxorubicin 50 mg/m(2), vincristine 1.5 mg/m(2), and prednisolone 40 mg (4 x CVAP) for 5 days. Clinical tumor response was assessed. Those who responded (complete response [CR] or partial response [PR]) were randomized to receive further 4 x CVAP or 4 x DOC (100 mg/m(2)). All nonresponders received 4 x DOC. RESULTS One hundred sixty-two patients were enrolled; 145 patients completed eight cycles of NA CT. One hundred two patients (66%) achieved a clinical response (PR or CR) after 4 x CVAP. After randomization, 50 patients received 4 x CVAP and 47 patients received 4 x DOC. In patients who received eight cycles of CT, the clinical CR (cCR) and clinical PR (cPR) (94% v 66%) and pathologic CR (pCR) (34% v 16%) response rates were higher (P =.001 and P =.04) in those who received further DOC. Intention-to-treat analysis demonstrated cCR and cPR (85% v 64%; P =.03) and pCR (31% v 15%; P =.06). Axillary lymph node examination revealed residual tumor in 33% of patients who received 8 x CVAP and 38% of patients who received further DOC. In patients who failed to respond to the initial CVAP, 4 x DOC resulted in a cCR and cPR rate of 55% and a pCR rate of 2%. Forty-four percent of these patients had residual tumor within axillary lymph nodes. CONCLUSION NA DOC resulted in substantial improvement in responses to DOC.

Abstract
In order to establish a therapeutic approach for primary breast cancer of medial and central origin, we reviewed 183 patients who had been treated by one of the following three modalities at the Second Department of Surgery, Osaka University Medical School between January, 1965 and December, 1980. Group A (n = 70): standard radical mastectomy alone; Group B (n = 34): standard radical mastectomy followed by postoperative irradiation to the parasternal and supraclavicular regions, and; Group C (n = 62): extended radical mastectomy that included removal of the parasternal lymph nodes. The background factors of the three groups were not significantly different. The overall survival five and ten years following surgery in the three groups were 91 percent and 79 percent in group A, 82 percent and 67 percent in group B, and 82 percent and 70 percent in group C, respectively, showing no significant difference in overall survival among the three groups. When the patients were classified according to the extent of axillary lymph node involvement, there was no difference in survival among the three treatments in patients who had less than three lymph node metastases in the axilla. However, treatment of the parasternal lymph nodes improved survival in the patients who had more than four lymph node metastases in the axilla. Parasternal lymph node involvement definitely worsened the prognosis, showing it to be a good prognostic factor. Thus, extended radical mastectomy should be considered for patients with breast cancer of medial or central location, when extended axillary lymph node involvement is found.

Abstract
A total of 254 patients with stages T1-3a/N0-1/M0 operable breast cancer were randomized to either surgery alone or surgery plus adjuvant chemoimmunotherapy (LMF + BCG). Ten-year results are presented for RFS (relapse-free survival) and OAS (overall survival) in the whole patient population as well as in the most important menopausal and nodal subgroups. LMF + BCG significantly increased RFS in the whole patient population as well as in node-positive women. The earlier impressive RFS and OAS gains for node-negative patients were fading after 5 and 8 years respectively, leaving marginal trends in favour of the LMF + BCG treated women. Node-positive patients treated with LMF + BCG continue to demonstrate a marginal gain in RFS up to 10 years. This gain is nearly exclusively expressed in postmenopausal node-positive women, an observation which can be made in the node-negative patient group as well. Despite the still continuing increase in RFS,' no OAS benefit was observed for node-positive women with LMF + BCG at any time of the study. Dose still remains a critical factor in cancer therapy. However, at 10 years of follow-up, a full dose of LMF (greater than or equal to 90%) during the six cycles no longer affects OAS favourably. There was no indication of any adverse long-term toxicity of LMF + BCG in our study after a median follow-up of 10 years, especially no increase of second tumours. In the node-negative patient population, the presence or absence of intramammary lymphatic infiltration seems to be a significant prognostic factor within this nodal subgroup.

Abstract
The therapeutic cure of breast cancer involves local and metastatic control. In the past they have been conceptually separated with local control being considered the focus for primary therapy and metastatic control an issue only at the time of relapse. With new understanding of tumor cell biology and the natural history of breast cancer, it has been recognized that the two issues cannot be easily separated. The emotionalism that has accompanied breast cancer research, and its results, both within the oncologic community, and in the public mind, have made the design, interpretation, and analysis of breast cancer trials a difficult area. The author reviews the existing clinical trial literature base in primary therapy and attempts to develop its therapeutic implications.

Abstract
A randomized surgical adjuvant trial in 242 evaluable patients with T1-3a, N0-1, and M0 breast cancer was initiated 4 years ago. The well-tolerated, oral combination chemotherapy with six cycles of Leukeran plus methotrexate plus fluorouracil (LMF) plus repeated BCG skin scarifications was used. After 4 years, the following results were seen: (1) significant increase of relapse-free (RFS) and also overall survival (S) in both pre- and postmenopausal node-negative patients versus surgical controls (RFS 91.1 vs. 701%, P = 0.003; S 96 vs. 88%, P = 0.03); (2) no significant increase of RFS or S in pre- and postmenopausal node-positive patients versus surgical controls (RFS 50.1 versus 44%, P = 0.49; S 70 versus 68 %, P = 0.9, respectively); (3) Patients receiving greater than 90% of the planned LMF dose showed significantly better survival after 4 years; and (4) Nonrandomized comparison with concurrent Swiss adjuvant studies with LMF alone indicate no beneficial or harmful effect of BCG skin scarifications in addition to the six-cycle LMF.

Abstract
The results of a comparative study of a series of 15,132 cases of breast cancer diagnosed in 1972 and a series of 14,577 cases diagnosed in 1977 are presented. Data were collected through surveys of 670 hospitals in the United States conducted by the Commission on Cancer--American College of Surgeons. There has been significant improvement in the stage at which breast cancer is diagnosed in black patients. The proportion of cases diagnosed at the localized stage increased from 38.5% in the 1972 series to 45.2% in 1977. During the same time period, the average size of the tumor in black patients decreased from 4.5 cm to 3.5 cm and the average number of positive axillary nodes decreased from 6.6 to 5.5. Less change in the stage of disease at diagnosis or in the size of the tumor was observed in white patients and no significant change was found in the average number of positive axillary nodes. The average number of axillary nodes examined increased from 14.5 nodes to 16.0 nodes in white patients and from 16.4 to 17.3 in black patients. The proportion of all cases treated by surgery with axillary dissection increased from 79.8% in 1972 to 85.8% in 1977. Recent cases were more likely to be treated with surgery alone. Use of radiotherapy alone or in combination decreased for both races but the use of chemotherapy increased. A marked shift from Halsted radical mastectomy to modified radical mastectomy was evident at every level of age, stage of the disease, and size of tumor, and was observed in hospitals of all sizes. A significant increase in the average number of nodes examined was observed for each surgical procedure involving axillary dissection. No increase was observed in the use of conservative surgery (wedge excision, total mastectomy, or total mastectomy with low axillary dissection).

Abstract
Progressive improvements in the management of certain paediatric and haematological malignancies have provided guidelines for the current approaches to the management of the more common solid tumours of adults. These include precise histopathological grading; comprehensive evaluation of extent of disease; staging classifications accurately correlated with prognosis and progressive evaluation of available therapeutic modalities for all stages of disease in an attempt to define the best combination of local and systemic forms of therapy. Breast cancer is reviewed in detail as an example of the more responsive tumours where screening programs; improvements in pathological and clinical staging and the introduction of systemic chemotherapy together with optimal use of other methods of treatment for the various stages of disease gives hope for a significant improvement in long term survival statistics. Lung cancer has also been reviewed as an example of the more resistant types of cancer where screening programmes and current therapy including the use of combination chemotherapy have given minor encouragement but not had a definite influence on long term survival. Some further gains may still be achieved with currently available techniques but major improvements will probably require the development of better therapeutic tools including radiotherapy with high linear energy transfer particles; new chemotherapeutic agents and specific forms of immunotherapy. It is also quite possible that completely different forms of therapy for these resistant tumours will be necessary to reach the desired goal of long term improvements in survival.

Abstract
The best combination of methods for managing primary breast cancer may not yet be known. Radiation therapy has been proved effective in decreasing the incidence of local and regional recurrence following mastectomy. Thus, until a superior regimen is established, I recommend local and regional irradiation for patients at high risk for recurrence. Local irradiation is also an effective means of achieving palliation of symptoms associated with metastatic disease.
