Are modified radical mastectomies done for T1 breast cancers because of surgeon's advice or patient's choice?

Clinical trials show that T1 breast cancers are equally well treated with breast-conserving surgery as with modified radical mastectomy. However, the Colorado Central Cancer Registry indicates that, for the past 5 years, the majority of women (72%) with T1 breast cancer in Colorado have undergone modified radical mastectomies. A questionnaire was sent to 175 general surgeons to determine the reasons for the high number of modified radical mastectomies still being performed. The results indicate that one group of surgeons (34% of those responding) believes each type of surgery has equal survival rates but unknowingly influences the patient to choose modified radical mastectomy, with a subtly biased presentation. Education of both surgeons and patients is needed to increase the number of patients with T1 breast lesions who can benefit from breast-conserving therapy.

[A clinical study of 214 cases of modified radical mastectomy with preservation of major and minor pectoral muscles].

OBJECTIVE: To study clinical effects of modified radical mastectomy with preservation of major and minor pectoral muscles. METHODS: A retrospective analysis was carried out in 214 cases of breast cancer patients (including stage I 66 cases, stage II 141 cases and stage III 7 cases). Modified radical mastectomy with preservation of major and minor pectoral muscles was performed on all the patients. RESULTS: Out of 214 cases, 12 (5.6%) had subcutaneous fluid, 16 (7.4%) had skin flap margin necrosis. Upper limb lymphatic edema was found in 8 (3.7%) patients, and pectoral muscle contracture with dyspraxia of upper arm occurred in 11 (5.1%) cases. Three year survival rate was 82.3% and five year survival rate was 63.4%. For stage I patients, the five year survival rate attained to 79.6%, and stage II 56.3%. CONCLUSIONS: Preservation of lateral branch of pectoral nerve can avoid complication of pectoral muscle contracture with dyspraxia of upper arm. Early chemotherapy of postoperation prevents breast cancer occurrence and metastasis. Comprehensive treat approaches for operative wound avert subcutaneous fluid, and complex therapy improves long-term effect of breast cancer patients.

Survival following breast-conserving surgery and irradiation or modified radical mastectomy in patients with invasive breast cancers with a maximum diameter of 1 cm.

The reported relapse-free survival for women with invasive breast cancers measuring no more than 10 mm in dimension ranges from 75% to 95%, with axillary status an important prognostic factor in most series. Further study of prognostic variables in this most favorable subset is notably limited. We retrospectively reviewed the records of 168 women with invasive breast cancers < or = 10 mm treated with either breast conserving surgery+axillary dissection (AXD) and radiation therapy, or mastectomy+AXD. The actuarial survival and survival free of distant metastases (DMFS) at 7 years was 95% and 97%, respectively. Location and size of the primary tumor were most important in predicting outcome, although statistical significance was not achieved. The 5-year distant metastases-free survival (DMFS) was 100% for central and inner quadrant tumors, compared to 97% in those with outer quadrant tumors, p = 0.18. The 5-year DMFS was 100%, 95%, and 98% for patients with cancers 2-5 mm, 6-9 mm, and 10 mm, respectively, p = 0.15. Status of the axillary lymph nodes, type of breast surgery, clinical tumor status (palpable vs. nonpalpable), age, menopausal status, histologic grade, systemic therapy, or histologic type were not found to have a significant impact on prognosis.

Modified radical mastectomy with immediate breast reconstruction.

The authors reviewed 100 consecutive patients with breast cancer treated by modified radical mastectomy and immediate breast reconstruction in order to assess the safety and efficacy of this procedure in terms of cancer control. The study began in 1978 and is continuing. The procedure involves a two-team approach with both the general surgeon and the plastic surgeon interviewing the patient preoperatively. Virtually all breast reconstruction involved the use of a submuscular silicone saline type of implant. The median follow-up is 36 months. Slightly over half of these cases were Stage 0 or Stage I. There have been eight recurrences, including five local or regional and three distant. No patient has died of her disease at this point. Cosmesis was equal to or superior to that seen in delayed breast reconstruction. There have been no hidden recurrences. Postoperative depression has been significantly less. We conclude that modified radical mastectomy with immediate breast reconstruction is a safe and effective alternative to modified radical mastectomy alone.

[Electrophysiological study on the atrophied pectoralis major muscle after modified radical mastectomy].

In order to clarify the cause of the atrophy of the pectoral muscles after modified radical mastectomy, twenty patients who had had the operation at Nagasaki Chuo National Hospital 40 days to 2 years prior to this study, were investigated by electromyography. Of 20 subjects, 11 had the operation to preserve the pectoralis major muscle and 9 had the operation to preserve both the pectoralis major and minor muscles. The results were as follows: 1) Electromyography revealed some damages to the pectoral nerves in 16 cases of 20 (80%). In 12 cases, development of fibrillation potentials was observed at rest, while motor unit potentials disappeared during voluntary contraction. These findings suggest the damage to the nerves including neutrotomy. 2) The regions with macroscopic muscular atrophy remarkably coincided with those with neurogenic changes on electromyography. This suggests that the atrophy of the pectoralis major after modified radical mastectomy might be mainly caused by the damage to the pectoral nerves. 3) The mastectomy preserving only the pectoralis major tends to cause damage to nerves innervating the sternocostal part of the pectoralis major more frequently than the mastectomy preserving both the pectoralis major and minor muscles. The abdominal part was frequently damaged irrespective of the types of the operation.

Five-year results of a randomized clinical trial comparing modified radical mastectomy and extended radical mastectomy for stage II breast cancer.

A controlled cooperative study was carried out to assess the value of modified radical mastectomy for patients with stage II breast cancer. The data was analyzed from 11 institutions in the Shikoku District participating in a prospective clinical trial in which patients were randomly assigned either to a modified radical mastectomy group or an extended radical mastectomy group. These two groups of patients were similar to each other in terms of such background factors as age distribution, menopausal status, TNM classification, tumor size, location of the primary tumor, axillary nodal involvement, histological type, and estrogen receptor status. The median follow-up times in the modified and extended radical mastectomy groups were 4.7 and 4.5 years, respectively. The cumulative curves indicated no difference between the two groups in either disease-free survival or overall survival. The survival rates were classified according to the presence or absence of axillary nodal metastases. However, no significant difference was found between the two groups. These findings thus suggest that the routine removal of the grossly uninvolved major pectoral muscle and parasternal lymph nodes is not necessary in patients with stage II breast cancer.

Modified radical mastectomy sparing one or both pectoral muscles in the treatment of breast cancer: intra and postoperative complications.

CONTEXT AND OBJECTIVE: Modified radical mastectomy is widely utilized in breast cancer treatment. However, no prospective comparison has yet been made between the Madden technique (preservation of the pectoralis minor muscle) and the Patey technique (resection of this muscle). The aim of this work was to compare these two modified radical mastectomy techniques, by analyzing their degrees of difficulty and complications. DESIGN AND SETTING: Randomized trial at the Breast Unit of Hospital Araújo Jorge, Goiás; and Faculdade de Medicina da Universidade Federal de Goiás. METHODS: 430 patients with breast cancer with an indication for modified radical mastectomy were included in the program, of whom 426 patients were available for analysis (225 allocated to Patey and 201 to Madden). The chi-squared and Student t tests were used for analysis. RESULTS: The patients demographics were well balanced between the two groups. The mean duration of the surgical procedures was 105 (+/- 29.9) and 102 minutes (+/- 33), for the Patey and Madden groups, respectively (p = 0.6). Hospitalization duration was 2.3 days for both groups. The mean number of lymph nodes resected was 20.3 (+/- 7.6) for Patey and 19.8 (+/- 8.1) for Madden (p = 0.5). There were no differences in terms of vascular or nerve sections, hematomas or infections. The surgeons reported the same degree of difficulty for the two methods. CONCLUSION: The removal of the pectoralis minor muscle did not influence any of the variables studied. Therefore, either technique can be performed, at the surgeon's discretion.

Locoregional recurrences after 649 modified radical mastectomies: incidence and significance.

A continuous series of 649 patients, treated by modified radical mastectomy for primary breast carcinoma, is analyzed after a median follow-up of 92 months. 'True isolated' locoregional recurrences (LR), defined as LR not preceded or followed by distant metastases within 6 weeks, appeared with a cumulative actuarial incidence rate of 6%, 14% and 19% after 1, 5 and 7 years respectively, whereas the respective figures for distant metastases (M1) were 10%, 37% and 48%. The main initial parameters, predicting both the LR-free and the M1-free interval, are presented by statistical analyses in the following order of importance: number of invaded lymph nodes in the axilla, tumor size (T) and histological grading of differentiation. The same factors also predicted the imminence of M1 once LR had occurred, as well as survival after LR. A higher incidence of M1 after LR was also correlated with estrogen-receptor negative tumors and with those LR occurring within one year after mastectomy. LR occurred at the chest wall (65%), in the sub-clavicular fossa (16%) and the axilla (6%); the remaining 13% occurred in two of the sites. There was a trend towards longer survival after chest wall recurrence than after LR recurrence at another site. Axillothoracic irradiations postmastectomy gave a lower rate of LR in 227 patients than did a regimen of 12 months adjuvant chemotherapy with irradiation restricted to the internal mammary lymph nodes in 120 subsequent patients: 17 vs 25% at 5 years (P = 0.03 when adjusted by initial nodal involvement and T-size). Total excision of LR (repeated if new LR occurred) gave better rates of local ultimate control and survival than other kinds of treatments, with or without adjuvant local or systemic therapy. LR is not always a sign of imminent generalized disease. Actuarial 5-year survival after LR is 26.2% overall whereas, if only 'true isolated' LR are considered, the survival is 37%.

Effect of fibrin glue on lymphatic drainage after modified radical mastectomy: a prospective randomized trial.

Fibrin as a tissue sealant has been used since the turn of the century for hemostasis. The development of cryoprecipitate and the resultant availability of higher concentrations of fibrinogen have led to a resurgence of interest in this material. Fibrin glue has since been shown to be effective for numerous applications throughout the field of surgery. Animal studies have shown fibrin glue to be effective at reducing drain output after mastectomy. Human studies, however, have been equivocal. Our objectives were to determine whether the use of fibrin glue would decrease lymphatic drainage after modified radical mastectomy and subsequently reduce time to drain removal. A prospective randomized trial was conducted consisting of 27 women. All women received modified radical mastectomy. At the completion of the mastectomy they were randomized to receive either standard closure or the application of fibrin glue before standard closure. Patients were then monitored for daily drain output, time to drain removal, and wound complications. A total of 14 women received fibrin glue and 13 received no glue. Those patients receiving fibrin glue had a significantly higher average drain output than patients who did not receive glue (1308 vs 754 cm3; P = 0.012). Time to drain removal was also increased by 4 days, although this did not reach statistical significance. The overall complication rate was higher for the fibrin glue group, although again, this did not reach significance. The application of fibrin glue significantly increased drain total drain output after modified radical mastectomy. Time to drain removal was increased as was the complication rate. On the basis of these data fibrin glue cannot be recommended for routine use in modified radical mastectomy.

[The value of radiotherapy after modified radical mastectomy. 10-year results of the Heidelberg study].

Modified radical mastectomy was performed in 142 female patients with operable carcinoma of the breast. One of the two prospectively randomised groups received postoperative radiotherapy with 6000 rad. Survival rates were equal for both groups. Follow-up radiotherapy had a beneficial influence on survival rate and rate of distant metastases in median tumour sites. In lateral tumour localization the course of disease was less favourable with radiotherapy than without. Local relapse rates were slightly, however not significantly, lower after irradiation. The decisive prognostic criterium is T- and N-stage at the time of diagnosis.

The technique of modified radical mastectomy.

The functional and cosmetic results of this modified radical mastectomy are superior to those achieved by standard radical mastectomy. The incidence of lymphedema of the ipsilateral arm, which is one of the feared complications from a standard radical mastectomy, appears to be decidedly less.

Non-tumour morbidity and mortality after modified radical mastectomy.

From 1985 to 1987 148 patients underwent mastectomy for breast cancer, of whom 91 underwent modified radical mastectomy. Of these patients (median age 60 years (range 31-86 years)), 89 have been assessed for early (< 30 days) and late (> 30 days) non-tumour morbidity and mortality. A total of 41 patients had nodal metastases. Adjunctive therapy used was tamoxifen in 70 patients and radiotherapy in 20. Overall, 47 patients (53%) developed a total of 75 complications, and there was one 30-day mortality. Of the patients, 26 developed one complication, 14 had two complications and 7 three complications. Early complications were lymphocoele/seroma (n = 22), wound infection (n = 9) and cardiopulmonary problems (five deep vein thrombosis, two pulmonary embolus (1 death), one myocardial infarct). Late complications were lymphoedema (n = 10), pectoralis major wasting (n = 6), frozen shoulder (n = 7), intercostobrachial neuralgia (n = 4), and a small number of self-limiting wound problems (n = 9). There were two late deaths (myocardial infarcts). Early complications were not related to nodal status, and late complications were related to neither nodal status nor radiotherapy. Significant morbidity is attached to radical surgery for breast cancer. Most complications are minor and self-limiting, but there are a small number of late complications which may affect quality of life.

Comparison of partial and modified radical mastectomy in the community setting--"10 years later".

Conservative surgery followed by postoperative radiation is considered equivalent to a modified radical mastectomy (MRM) for the treatment of early breast cancer. It cannot be assumed that results from selected academic centres are equivalent to those obtained in the general community setting, because there may be differences in patient selection or surgical or radiotherapy techniques that may adversely affect outcome. A quality-control study of women who were seen at the British Columbia Cancer Agency and were treated by partial mastectomy (PM) was begun in 1983. Eighty-four women who underwent conservative surgery between January 1979 and November 1982 and were referred to the British Columbia Cancer Agency were matched with 84 women who underwent MRM. The mean follow-up was 10.5 years. At 10 years disease-free survival in both groups was 63%. Survival overall for the PM group was 72.6% and for the MRM group was 69%. The survival rate decreased with increasing size of the tumour and increasing number of nodes. In women with lymph-node involvement there was a survival advantage for those treated by PM and radiation compared with those treated by MRM. The woman's age at diagnosis did not affect these findings. Recurrence and complication rates were similar in both groups, and treatment was considered equivalent.

[Conservative therapy of I and II stage breast cancer--successful alternative to modified radical mastectomy].

A clinical trial was conducted at the Center's Clinic to compare breast conserving treatment (quandrantectomy + radiation) (BCT) with modified radical mastectomy (M). It included 190 patients with stage I-II carcinoma up to 30 mm (BCT with "negative margin"--122; M--68). All the patients had undergone full axillary dissection. Mean total dose of 48.8 Gy was delivered to the whole breast by means of an external beam. No boost to tumor bed was given. Forty-one percent of tumors in the mastectomy group were of medial or central localization. The locoregional recurrence rates were significantly different (BCT--4.09 vs. M--20.5%; p < 0.001). However, the differences between distant metastasis occurrence and 5-year survival were not (BCT--4.91 and 95.6%; M--11.76 and 91.8%; p > 0.5, respectively). Nor were they significant for the localization/5-year survival relationship: lateral breast tumor--92%, medial--100% and central--89% (p > 0.6).

A comparative study of modified radical mastectomy using harmonic scalpel and electrocautery.

AIM: The harmonic scalpel is recently emerging as an alternative surgical tool for dissection and haemostasis and has been extensively used in the field of minimally invasive surgery. We studied the utility and advantages of this instrument over electrocautery for performing modified radical mastectomy. METHODS: The operative and morbidity details of twenty-three breast cancer patients who underwent modified radical mastectomy using the harmonic scalpel were compared with 23 matched controls operated with electrocautery by the same surgical team. RESULTS: There was no significant difference in the operating time between the harmonic scalpel and electrocautery group (104 and 100 mins, p > 0.05). The blood loss (60 +/- 35 ml and 294 +/- 155, p < 0.001) and drainage volume (590 +/- 430 ml and 1,085 +/- 690 ml, p < 0.001) were significantly lower in the harmonic scalpel group. There was a significant reduction of drain days in harmonic scalpel group (mean five and nine days, p < 0.05). There was no significant difference in the seroma rate between two groups (16% and 22%). CONCLUSION: Modified radical mastectomy using harmonic scalpel is feasible and learning curve is short. Harmonic scalpel significantly reduces the blood loss and duration of drainage as compared to electrocautery.
