Factors affecting survival following radical mastectomy.

Data on 17 potentially useful factors from 152 women undergoing radical mastectomy for operable breast cancer were analyzed in order to determine the effect of each on survival and their relative importance. Only four, clinical stage, clinical and pathological lymph node involvement, and appearance of recurrence and metastases, proved to be of significant prognostic value. Axillary nodal involvement was the main single determinant of survival. Multiple regression analysis, based on factor analysis of the original input variables, was able to account for 34% of the variance in survival and is thus of only very limited use as a predictive instrument in the clinical management of prospective patients.

Mammary carcinoma--multidisciplinary treatment with bilateral mastectomy and immediate reconstruction.

The classical concepts pertaining to the natural history of mammary carcinoma and its treatment must be reviewed if survival rate is to be improved. By the time diagnosis is established, a fair amount of cases of carcinoma of the breast present distant, clinically undetectable micrometastases, which will not be affected by local therapy (surgery or radiation). Increasing evidence shows that mammary carcinoma nowadays must be looked upon as a diffuse disease affecting both breasts. Postoperative radiation does not improve the 5- and 10-year survival rates and has a negative effect upon the immunological defense of the patient. Immunology plays an important role in the evolution and cure of the patient with carcinoma of the breast. The mutilation produced by radical or ultraradical mastectomy may throw the patient into mental depression which, as a consequence, may decrease the immunological competence of the patient. Multiple drug chemotherapy, started at the time of surgery and continued for several months thereafter, may kill micrometastases. Preventive immunotherapy seems to be beneficial to the patient in attempting control of metastases.

Relationship between body weight and the incidence of positive axillary nodes at mastectomy for breast cancer.

The question, whether obesity is associated with an increased incidence of positive axillary nodes at mastectomy for breast cancer, was studied in two quite different hospital populations; one from a large urban teaching hospital (Montefiore) and one from a medium-sized Air Force medical center (Malcolm Grow). In the Montefiore population, the answer was "yes"; 67% of the node-positive patients, but only 31% of the node-negative patients were obese (20% or more above ideal weight) (p less than 0.05). In the Malcolm Grow population, the answer was "no"; 20% of the node-positive and 20% of the node-negative patients were obese. The different answers, we believe, are due to the biological differences between the populations; the Montefiore population was shorter (by an average of 1.7 inches), heavier (by an average of 20 lbs), and more obese. The incidence of obesity was about three times as high in the Montefiore population (52% versus 20%; p less than 0.02) and it contained a statistically distinct subpopulation of obese patients, while the few obese patients in the Malcolm Grow population constituted merely the upper tail of a unimodal log-normal distribution of weight in that population. We propose that it is possible to demonstrate a relationship of obesity to node-positivity in the Montefiore population but not in the Malcolm Grow population because obesity was highly prevalent in the former and almost nonexistent in the latter. It seems self-evident that it is not possible to demonstrate an effect of obesity in a population if that population manifests no significant obesity, statistically speaking, but disregarding this principle, we believe, may account for the controversy in the literature about whether obesity is a risk factor in breast cancer.

Local recurrence in the pectoralis muscles following modified radical mastectomy for carcinoma.

Local recurrence following treatment of carcinoma of the breast is usually associated with systemic metastases. However, there are some cases in which local disease is the only manifestation of recurrence, and long-term survival can be achieved in these patients with aggressive treatment. Ten cases of apparent isolated metastasis in the pectoralis muscle following modified radical mastectomy are presented and good results were obtained in some cases utilizing surgery or x-ray therapy or a combination. It is worth noting that reconstruction would not have interfered with the detection of these recurrences, if the implant had been placed under the muscle.

Intravenous nitrogen mustard given immediately after mastectomy: possible effect on local recurrence.

A small group of patients with Stage I and II ductal breast carcinomas were treated with intravenous nitrogen mustard the day of mastectomy and the first two postoperative days. Long term follow-up revealed that only one patient developed isolated local recurrence, a rate much lower than usually reported. It is possible that early use of chemotherapy could reduce local recurrences in the recently traumatized tissue.

Early drain removal following modified radical mastectomy: a randomized trial.

The dilemma of increasing costs of medical care and shrinking health budgets has stimulated attempts to implement stricter control on expenditure without affecting the quality of care. This study shows that in patients with operable breast cancer, a policy of early discharge after a mastectomy did not have deleterious effects on wound healing and was well accepted by patients. In a randomized trial, drains were removed after either 3 or 6 days postmastectomy, and in both groups of patients there was no difference between the mean volumes of seromas aspirated or the number of aspirations and return visits to the hospital. This suggests that a policy of early discharge is safe, acceptable, economical, and may improve bed utilization.

Mastectomy patients' decision-making for or against immediate breast reconstruction.

This multi-centred study examined how 93 women due to undergo mastectomy had elected for (n=37) or against (n=56) immediate breast reconstruction. Initial semi-structured interviews were conducted prior to undergoing surgery whilst follow-up interviews 6 and 12 months later examined particpants' experiences of surgery and their views on their decision. Three decision-making styles were identified. Most women (76) reported making quick, 'instant' decisions, whilst 14 sought further information before making their choice. Three women deliberated over their options and found decision-making particularly difficult.Decision-making was influenced by the perceived salience of alternatives, prevailing 'norms' regarding surgical practice within each hospital system and interactions with health professionals. Experiences of surgery often failed to match patients' pre-surgical expectations and the process of adjusting to the impact of surgery continued throughout the following year, during which women contended with a range of problems including pain, scarring and adjusting to a reconstructed breast. However, most women reported themselves satisfied with their decision and justified their choices by focussing on positive aspects of their surgery.Whilst many women make a quick decision about breast reconstruction, research needs to explore ways of facilitating decision-making amongst those who find this decision particularly difficult.

Effect of fibrinogen and thrombin concentrations on mastectomy seroma prevention.

Seroma formation remains a significant clinical problem which increases morbidity and hospital costs in patients undergoing mastectomy operations. This study evaluated the effect of varying the concentrations of fibrinogen and thrombin in fibrin sealant on successfully preventing seroma formation in a rat model. After axillary dissection, control animals (Groups I and II) had 1 ml of either normal saline or thrombin (100 U/ml) applied to the axilla while treated animals (Groups III-VIII) had increasing concentrations of 0.5 ml of fibrinogen (25, 50, or 100 mg/ml) and 0.5 ml of thrombin (10 or 100 U/ml) applied. Seroma volumes (means +/- standard deviation) were measured on Postoperative Day 5. They were largest in Group I (3.1 +/- 1.9 ml, n = 13) and Group II (3.9 +/- 2.7 ml, n = 15) and then decreased from a high in Group III (2.5 +/- 2.4 ml, n = 15) using fibrinogen, 25 mg/ml, and thrombin, 10 mg/ml, to a low in Group VIII (0.8 +/- 1.0 ml, n = 15) using fibrinogen, 100 mg/ml, and thrombin, 100 U/ml. Analysis of variance revealed a statistically significant difference in the mean seroma fluid volumes between the groups (P = 0.0021), while Scheffe's comparison showed a specific significant difference (P = 0.028) between the thrombin control (Group II) and the highest concentration fibrin sealant (Group VIII). The difference in seroma volumes for all control animals (Groups I and II), 3.5 +/- 2.4 ml, and all treated animals (Groups III-VIII), 1.7 +/- 2.1 ml, was highly significant by unpaired t test. (P < 0.0001). Thus, fibrin sealant was useful in reducing seroma formation in this rat model with the highest concentration of fibrinogen and thrombin appearing most effective. These data may be useful in guiding future clinical trials in humans.

Bilateral prophylactic mastectomy decision making: A vignette study.

BACKGROUND: Little is known about the perception of bilateral prophylactic mastectomy (BPM), and whether perceptions are influenced by a family history of breast cancer. It is also unclear what factors may play a role in selecting BPM for follow-up care. METHODS: Samples of predominantly Caucasian, well-educated women with (n = 129) and without (n = 104) family histories of breast cancer were provided a vignette of a woman at increased risk. They selected one of two follow-up options: (1) clinical breast examination, breast self exam, and annual mammography or (2) BPM. RESULTS: The samples did not differ on the decision to select BPM (29.5% vs 22.1%). The family history sample reported worry about breast cancer as a problem (34.4%) more often than women with no history (15.7%). Multivariate analysis found worry and estimated 10-year risk of the woman in the vignette as significant predictors of selecting BPM. CONCLUSIONS: Approximately 25% of our sample selected BPM as the preferred option. The majority supported the need to discuss BPM among women at increased risk. Finally, both factors associated with the selection of BPM (worry, risk assessment) are potentially amenable to psychosocial or educational approaches. There is a clear need for assessment of worry and risk perception prior to surgical decision making.

A randomized trial of postoperative five-versus three-drug chemotherapy after mastectomy: a Cancer and Leukemia Group B (CALGB) study.

The Cancer and Leukemia Group B (CALB) has conducted a randomized study of adjuvant chemotherapy in patients with breast cancer who have involved axillary nodes at the time of mastectomy. Five-drug treatment (CMFVP) was compared with three-drug treatment (CMF). For patients with more than three involved nodes, the CMFVP regimen produced a significantly prolonged disease-free survival in comparison to the CMF regimen.

Role of radiotherapy following total mastectomy in patients with early breast cancer. The Closed Trials Working Party of the CRC Breast Cancer Trials Group.

Between June 1970 and April 1975 the CRC (King's/Cambridge) Trial for early breast cancer randomized 2800 patients following mastectomy to immediate prophylactic radiotherapy (DXT group, n = 1376) or control (WP group, n = 1424). Although no difference in overall survival has been demonstrated, there is an increase in mortality in the irradiated patients from nonbreast cancer causes beyond 5 years. It is because of an increase in the number of deaths due to new nonbreast malignancies [RR V 1.89 (1.18-3.05)] and to cardiac-related disease [RR = 1.52 (1.01-2.29)]. This increased cardiac death rate may be related to the use of orthovoltage, which has greater scatter. There was a significant increase in risk for those with left-sided rather than right-sided tumors in this subgroup [chi 2 (int) = 5.08; p = 0.02]. Local relapse was significantly reduced in those patients randomized to radiotherapy [RR = 0.44 (0.39-0.51)]. Median survival following local relapse was 1.35 years in the DXT group and 2.66 years in the WP group (logrank p < 0.001). Patients with the first relapse in the supraclavicular nodes had a particularly poor prognosis (median survival: DXT 0.69 years; WP 1.37 years). Almost 50% of patients who have had a recurrence on the chest wall or in the axilla and subsequently died have had disease at the same site at death, regardless of whether they had radiotherapy immediately following surgery. However, the actual number of patients dying with persistent disease is halved by the use of prophylactic radiotherapy (DXT 66; WP 143). Classic pathological features such as tumor size, tumor grade, and nodal involvement help define those patients at high risk of local failure who should be recommended for immediate radiotherapy.

Distribution of doxorubicin to normal breast and tumour tissue in patients undergoing mastectomy.

Response to cytotoxic agents is assumed to be related to the concentration of drug achieved within tumour tissue. It is also often assumed that, given similar tissue concentrations of drug, normal tissues are less responsive to the same cytotoxic agents. This can partly be explained by the number of cells in normal tissues that are differentiated. These non dividing cells, in a stable testing phase of the cell cycle (G0) are less susceptible to cytotoxic damage. Little is actually known about the relationship between tumour drug concentrations and those in the tissue of the tumour-bearing organ. In this study, we compared doxorubicin concentrations in paired samples of tumour and normal breast tissue from 17 previously untreated women undergoing mastectomy. The relative cellularities of both specimens were estimated by measuring their DNA content. There was wide variation in intra-tumoural doxorubicin concentrations (range, 220-1,590 ng/g). Normal tissue also showed marked inter-patient variation (range, 81-1,000 ng/g). For a single patient the tumour drug concentrations were significantly higher than those in normal breast tissue (P less than 0.05), and tumour: normal tissue ratios ranged from 1.27 to 8.30. Where doxorubicin concentration was expressed in terms of the relative cellularity of the tissues, there was no significant difference between, drug concentrations in the tumour and those in normal breast tissue (tumour: normal ratios, 1.1:1.8). There was a significant correlation (r = 0.76, P less than 0.05) between peak serum values and tumour concentrations of drug. No correlation was found between drug concentrations achieved and the histological grade or oestrogen receptor status of the breast cancer.

Immediate reconstruction after subcutaneous mastectomy.

We describe an improved technique for subcutaneous mastectomy using two surgical approaches, one through a short axillary incision and the other through an inframmary incision. Pathological breast tissue is removed from the prepectoral space through the lower incision and a silicone implant is placed in the retropectoral space through the axillary approach. A further modification is described using a laterally rotated inframmary dermis flap to reinforce the lateral margin of the retropectoral space containing the prosthesis.

Immediate breast reconstruction with subpectoral implantation after transaxillary subcutaneous mastectomy for siliconoma.

Immediate breast reconstruction on 14 patients suffering from breast hardening after augmentation mammaplasty by injection of silicone gel was performed. Transaxillary subcutaneous mastectomy was done followed by insertion of a double-lumen prosthesis into the subpectoralis plane. The result was greatly influenced by the amount of injected silicone gel. The patient was carefully observed after surgery, and the prosthesis was immediately removed when abnormal skin changes became apparent. Seven cases had no hardening on either side and 1 case had hardening on one side, 3 cases had hardening on both sides and 1 case on one side, 2 cases had the prosthesis removed from both sides and 2 cases from one side. All other cases with hardening or prosthesis removal, except one with removal from both sides, were subsequently reconstructed after more than three months.

Redefined indications for subcutaneous mastectomy in patients with benign breast disease.

The indications for subcutaneous mastectomy have been redefined as a result of more recent and more conclusive data. This information has provided us with specific biological markers that define more clearly the high-risk woman for breast cancer. Proliferative disease, with and without atypia, should replace the previous criterion of moderate to severe fibrocystic disease or non-specific mammary dysplasia.

Comparison of pain, motion, and edema after modified radical mastectomy vs. local excision with axillary dissection and radiation.

Recent data suggest that prognosis is similar for women with primary breast cancer whether they receive modified radical mastectomy (MRM) or local excision and axillary dissection with radiation (XRT). The effects of either of these treatments on arm mobility, pain, or edema have not been compared. To assess the impact of MRM or XRT on mobility, pain, or edema, we evaluated patients treated in a prospective randomized trial designed to assess prognosis following MRM or XRT. All were provided a standardized physical therapy program including arm mobilization, shoulder strengthening, prevention and treatment of upper extremity edema, and education about arm function. Patients were evaluated for chest wall pain, arm motion, muscle strength, and edema as determined by circumferential measurements at the wrist, forearm, and arm. Evaluations were performed preoperatively and at yearly anniversaries of their surgery. Women receiving XRT had more chest wall tenderness at 1 and 2 years after surgery than those receiving MRM (p2 less than 0.0001 and p2 = 0.0007 respectively). Those receiving MRM were slower to reach their preoperative range of motion (ROM) (p2 = 0.043). Incidence of muscle weakness was similar in both groups. The few patients with local recurrence of tumor had more upper extremity edema than those who did not recur (p2 = 0.085) at 1 year and (p2 = 0.02) at 2 years. In patients who did not develop local recurrence, those who had received XRT had greater but nonsignificant increases in upper extremity circumferential measures compared with those receiving MRM at any anniversary evaluation. Patients receiving MRM and XRT are likely to have some differences in functional outcome.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparison of analgesic effect of locally and systemically administered ketorolac in mastectomy patients.

BACKGROUND: Ketorolac is a parenteral nonsteroidal antiinflammatory drug (NSAID). Two features have limited its clinical utility: tendency to elicit kidney failure and inability to produce complete analgesia. Because most NSAIDs are weak acids (pKa 3-5) and become concentrated in acidic tissues, such as injured and inflamed tissues, we hypothesized that local administration may enhance its analgesic efficacy while lowering the potential for systemic complications. METHODS: We conducted a randomized, placebo-controlled study of 60 group I-II (American Society of Anesthesiology criteria) mastectomy patients, 20 in each group. Near the end of surgery and every 6 h postoperatively, 20 ml of the study solution containing normal saline with or without 30 mg of ketorolac were administered simultaneously either via a Jackson-Pratt drain or intravenously in a double-blind fashion. The quality of pain control, the amount and character of the drain fluid, incidence of nausea and vomiting, length of stay in the postoperative care unit, and amount of morphine used for treatment of break-through pain were recorded. RESULTS: Intraoperative administration of ketorolac resulted in better quality of pain control in the immediate postoperative period regardless of route of administration. The incidence of nausea was significantly higher in the placebo group, and drain output in the ketorolac groups did not exceed the output in the placebo group. CONCLUSION: Analgesic of the locally administered ketorolac is equally effective to the efficacy of ketorolac administered intravenously.

Preincisional dextromethorphan decreases postoperative pain and opioid requirement after modified radical mastectomy.

PURPOSE: To examine whether preincisional dextromethorphan (DM) improved analgesia after modified radical mastectomy (MRM). METHODS: Sixty patients (ASA I-II) scheduled for MRM were included and randomly allocated into two groups. Patients in the treatment group (DM) received 40 mg DM and 20 mg chlorpheniramine maleate (CPM) i.m., and those in the control group received 20 mg CPM i.m. alone 30 min before skin incision. Meperidine, 1 mg x kg(-1) i.m., was given for postoperative pain relief as required. The time to first meperidine injection, total meperidine consumption, worst pain score, bed-rest time, and side effects were recorded every 24 hr for 48 hr after surgery by a resident anesthesiologist on a double-blind basis. RESULTS: A longer time to first meperidine injection (19.2 +/- 1.6 vs 1.5 +/- 0.23 hr, P < 0.001) and lower meperidine consumption (0[10] vs 75[50] mg, median [interquartile range], P < 0.001) were observed in the DM group than in the control group. The bed-rest time was shorter in the DM than in the control group (18.0[4] vs 23.0[19] hr, P < 0.001). No difference was noted in worst VAS pain score. Meperidine-related side effects (nausea, vomiting, pruritus, dizziness, headache) were more frequent in the control (10/30) than in the DM group (3/30, P < 0.05). The number of patients who required meperidine injection for pain relief was lower in the DM (7/30) than in the control group (25/30, P < 0.005). No DM- or CPM-associated side effects were observed. CONCLUSION: Preincisional IM. DM treatment decreased postoperative pain and opioid requirement after MRM surgery.
