Resectable breast cancer: axillary dissection sparing pectoralis muscles and nerves

In breast cancer surgery, axillary dissection is currently considered an essential step. Nevertheless, procedures commonly used include the resection of the pectoralis minor muscle and/or pectoralis nerves. Since 1984 we have performed axillary dissection by sparing both the pectoralis muscles and their nerves. In this paper we present the surgical technique. The comparison of the two groups with clinical N0 N1a assessment, the former of 103 patients submitted to this kind of surgical procedure, the latter (108 women) treated by resection of the pectoralis minor muscle, showed that the mean number of dissected lymph nodes in both procedures was superimposable.     

Transpectoral anterior approach to the axilla for lymph node dissection in association with mastectomy preserving both pectoral muscles and their neurovascular bundles

In Patey's mastectomy, which is still the most common operation for breast cancer, axillary node dissection (AND) is performed through the base of the axilla after retracting the pectoralis major muscle and excising the pectoralis minor muscle (some surgeons preserve the latter). This has the disadvantage of inadequate exposure of the axilla and the risk of damage to the neurovascular bundles supplying the pectoral muscles, which in the long run may lead to atrophy of these muscles. A transpectoral anterior approach to the axilla for AND in association with mastectomy was attempted in 115 cases to obviate the above-mentioned disadvantages. The approach included: 1) splitting of the pectoralis major between the clavicular and sternal fibers; 2) mobilization and swinging of the pectoralis minor into different directions by means of a sling to facilitate AND at selected levels. The major advantages of this approach were: 1) total preservation of both pectoral muscles with their neurovascular bundles maintained the normal anatomy and function of the shoulder; 2) the axilla was directly approached through the anterior wall instead of through the base; in this way the axillary contents were exposed almost at surface level; 3) the dissection plane could be limited to anterior to and below the axillary vein and the risk of postoperative lymphedema could thus be minimized; 4) change of position of the ipsilateral arm was not necessary; 5) the duration of surgery was reduced. Monoblock ablation of significant and suspected tissues, maintaining the normal anatomy and function of the shoulder, could be easily accomplished with this approach.

Effect of a mixed solution of sodium hyaluronate and carboxymethyl cellulose on upper limb dysfunction after total mastectomy: a double-blind, randomized clinical trial

Restricted shoulder mobility is a major upper limb dysfunction related to lower quality of life and disability after breast cancer surgery. We hypothesized that sodium hyaluronate?Ccarboxymethyl cellulose (HA?CCMC) applied to the surface of the pectoralis major muscle after mastectomy would significantly reduce pain and improve range of motion (ROM) of the shoulder in breast cancer patients. We conducted a double-blind, randomized controlled study to evaluate the clinical efficacy and safety of HA?CCMC in the prevention of upper limb dysfunction after total mastectomy (TM). A total of 99 women with breast cancer were randomly assigned to one of two groups. In the HA?CCMC group (n?=?50), a mixed HA?CCMC was applied to the surface of the pectoralis major and serratus anterior muscle after TM. In the control group (n?=?49), TM was performed without the use of HA?CCMC. The primary outcomes were ROM of the shoulder and motion-related pain assessed using a numeric rating scale measured before surgery (T0) and 3 (T1) and 6?months (T2) after surgery. Secondary outcomes included disabilities of the arm, shoulder, and hand (DASH) and the pectoralis minor length test. Compared with the control group, the HA?CCMC group showed greater reductions in postoperative restriction of total shoulder ROM (sum of flexion and horizontal abduction) at 3?months (10.20°, P?=?0.004). Mean pain levels related to flexion and horizontal abduction were significantly lower in the HA?CCMC group (?1.32 and ?0.93, respectively, P?<?0.05). The DASH score was lower (?4.94; P?=?0.057) in the HA?CCMC group at T2. No adverse effect was observed in either group. These results provide evidence that HA?CCMC may provide pain relief and improve ROM of the shoulder without causing adverse effects. The effect on pectoralis tightness should be investigated in further studies.     

Abnormal muscles that may affect axillary lymphadenectomy: surgical anatomy

Purpose The present study aimed at summarizing and presenting the anomalous muscles that a surgeon might encounter during axillary lymphadenectomy (AL). Methods For this purpose, both the anatomical and surgical literature was reviewed and an anatomical study on 107 cadavers was carried out. Furthermore, based on the anatomical features of the anomalous muscles that came up during our study and taking into consideration the landmarks of the AL, we further analyzed the complications that may arise from each of these muscles, along with their preoperative and intraoperative recognition and management. Results The literature review revealed that there are three supernumerary muscles that may affect the AL, namely the Langer’s axillary arch, the pectoralis quartus and the chondroepitrochlearis muscles, as well as the aplasia of the lower part of the pectoralis major muscle. Eight out of the 107 (7.48%) cadavers that we dissected had such an abnormal muscle in the axilla. Specifically, the axillary arch was found unilaterally in five cadavers (4.67%) and the pectoralis quartus muscle was present unilaterally in three cadavers (2.8%). One cadaver had both an axillary arch and a pectoralis quartus muscle in the right side. The abdominal and almost the whole sternocostal portion of the pectoralis major as well the pectoralis minor muscle were absent in one cadaver (0.93%). The chondroepitrochlearis muscle was not found in any of the cadavers that we dissected. Conclusions The present study offers the necessary preoperative knowledge for recognizing these muscles during AL, avoiding thus the complications that may arise from them.     

Modification of muscle-preserving radical mastectomy.

A technical improvement of the muscle-preserving radical mastectomy for breast cancer is presented. In this procedure, the Sulcus interpectoralis, located between clavicular and sternocostal parts of the pectoralis major muscle, is split bluntly and spread apart. Then, the pectoralis minor muscle is severed near its attachment to the coracoid process and an axillary dissection is thereby easily and thoroughly accomplished. The effectiveness of lymph node dissection by this method was ascertained when the number of the lymph nodes removed by this procedure was compared with that removed by the conventional muscle preserving mastectomy (Madden's operation) and the radical mastectomy. Ninety-three patients treated by this operation have shown a satisfactory cosmetic appearance and a good prognosis when compared with patients treated by the standard radical mastectomy.     

乳腺癌Patey术后胸大肌功能评估的意义

目的：探讨乳腺癌Patey术后胸大肌功能及保留胸肩峰血管的意义。方法：对21例资料完整行Patey手术的乳腺癌患者（手术组），应用肌电图仪对术后胸大肌功能进行动态检测，并以对侧正常胸大肌做对照。结果：肌肉自发电位显示手术组1个月第1、2、3、4位点，术后3个月和12个月第2、3、4位点肌肉自发电位增多。MUP时限显示第3位点，术后第1、3、12个月增宽例数增多。肌肉募集型显示第2点在术后1个月单保留组混合相增多，干扰相减少；第3位点术后1、3、12个月干扰相病例减少，单纯相及混合相病例增多。MUP波幅显示术后1个月胸大肌各部分MUP低波幅例数多。第3个月双保留组第2位点、手术组第3位点、单保留组第4位点MUP低波幅例数多。第12个月第3位点手术组MUP低波幅例数明显低于对照组。结论：Patey术后胸大肌各部分均存在不同程度的功能损害，但这些损伤绝大多数可在1年内恢复正常。切除胸肩峰血管对手术后远期的胸大肌功能恢复没有明显影响。     

Complete axillary lymph node dissection for stage I-II carcinoma of the breast

We reviewed the complete axillary dissection specimens of 136 patients with stage I-II breast cancer to clarify the distribution of axillary lymph node metastases in this disease. Our series included 71 patients undergoing axillary dissection as part of a modified radical mastectomy (MRM) and 65 patients undergoing axillary dissection in conjunction with conservative surgery of the breast and definitive postoperative breast radiotherapy (CAD). These two groups of patients were comparable according to age, menopausal status, tumor size, and clinical stage. In all patients the pectoralis minor muscle was excised and all axillary tissue removed. Each specimen contained a median of 23 lymph nodes. The axillary levels (I, II, III) were determined according to the relationship of axillary tissue to the pectoralis minor muscle (lateral, inferior, medial). Thirty-nine percent of the lymph nodes were contained in level I, 41% in level II, and 20% in level III. There were no significant differences noted in the number of lymph nodes or in the distribution of lymph nodes according to axillary level between dissections performed as part of the MRM or those done as a single procedure (CAD). Sixty-five patients (47.8%) had one or more positive lymph nodes in their axillary specimen. The clinical and pathologic stage was determined and compared for all patients. Among patients judged to have a clinically negative axilla, 37.6% had histologically positive lymph nodes (clinical false-negative rate). For patients with a clinically positive axilla, 11.1% had, histologically, no evidence of metastatic disease (clinical false-positive rate). When the distribution of lymph node metastases according to axillary level was studied, it was found that 29.2% of lymph node-positive patients (or 14.0% of all patients) had metastases only to level II and/or III of the axilla, with level I being negative (skip metastases). This incidence of skip metastases was greater among clinically node-negative than among clinically node-positive patients, but was not related to the size or location of the primary tumor in the breast. In addition, it was found that 20.0% of lymph node-positive patients (or 9.6% of all patients) were converted from three or fewer to four or more positive nodes by analysis of lymph nodes contained in levels II and III. This conversion from three or fewer to four or more positive nodes was due primarily to information contained in level II, with level III contributing to a smaller degree.(ABSTRACT TRUNCATED AT 400 WORDS)

改良带蒂胸大肌皮瓣修复头颈部晚期恶性肿瘤术后复杂缺损的临床应用

背景与目的：带蒂胸大肌皮瓣因为具有多种优点一直是头颈部组织缺损修复应用的经典组织瓣。当今,随着显微技术普及和提高,游离组织瓣逐步取代了带蒂组织瓣。然而,临床上并非所有病例均适宜接受游离组织瓣修复手术,邻近带蒂组织瓣更安全可靠。拟通过改进胸大肌皮瓣的制备及修复方法,探讨改良带蒂胸大肌皮瓣在修复头颈部晚期恶性肿瘤术后复杂缺损时的应用。方法：在皮瓣设计方案及制备方法等多方面改进胸大肌皮瓣,修复头颈部晚期恶性肿瘤术后复杂缺损患者51例。结果：51例改良胸大肌皮瓣全部存活,缺损区修复后外形和供区外形情况满意,缺损区功能得到良好的恢复,供区术后功能损伤最小化。结论：胸大肌皮瓣在设计及制备方法等多方面的改良,提高了对头颈部恶性肿瘤术后复杂缺损修复的范围及修复的距离,减少皮瓣坏死的概率,术后供区和受区外形、功能效果满意,目前仍然是头颈部恶性肿瘤术后缺损的重要修复手段之一。     

Low risk of locoregional recurrence of primary breast carcinoma after treatment with a modification of the Halsted radical mastectomy and selective use of radiotherapy

BACKGROUND: The purpose of the current study was to evaluate the locoregional recurrence rate after treatment of patients with operable breast carcinoma with a modification of the Halsted radical mastectomy and the selective use of radiotherapy and to identify risk factors for locoregional recurrence. METHODS: Between 1979-1987, 691 consecutive patients underwent mastectomy after a negative biopsy of the axillary apical lymph nodes. The median age of the patients was 59 years (range, 26-89 years). The clinical tumor size was < 2 cm in 72 patients, 2-5 cm in 387 patients, and >5 cm in 169 patients; 16 patients had a T4 tumor. Surgery was comprised of a modification of the Halsted radical mastectomy, including at least part of the pectoralis major muscle and the entire pectoralis minor muscle, in 573 patients; 303 patients had positive axillary lymph nodes. Adjuvant radiotherapy to the chest wall and regional lymph nodes was given to 74 patients, whereas an additional 414 patients underwent irradiation to the internal mammary and medial supraclavicular lymph nodes. The median follow-up was 91 months. RESULTS: The actuarial overall survival rate was 82% at 5 years and 63% at 10 years. The 10-year chest wall and regional lymph node control rates, including patients with prior distant failures, were 95% and 94%, respectively. The only two significant prognostic factors for locoregional recurrence on multivariate analysis were lymph node status and pathologic tumor size. CONCLUSIONS: Excellent locoregional control can be achieved with a modified technique of radical mastectomy in patients with negative apical biopsy and the selective use of comprehensive radiotherapy. These results may serve as a reference outcome for comparison with other locoregional treatment strategies.     

Prospective evaluation of pectoralis muscle invasion of breast cancer by MR imaging

BACKGROUND: Assessment of pectoralis muscle invasion is important for treatment planning for breast cancer. We evaluated the usefulness of breast magnetic resonance (MR) imaging for the detection of tumor invasion of the pectoralis muscle in breast cancer patients. MATERIALS AND METHODS: A total of 306 breast MR examinations were performed preoperatively. Three-dimensional gradient echo sequences, at a section thickness of 1.5 or 2 mm were obtained with administration of gadolinium-DTPA. All patients underwent surgery. RESULTS: In 33 breasts, disruption of the fat plane between tumor and muscle was noted. Seven of 33 cases showed muscle enhancement contiguous to enhanced tumors. Pathology reports indicated that 5 of 7 of the tumors involved muscle invasion. Of the 2 false positive cases, one showed muscle enhancement because of a previous biopsy, and the other was incorrectly interpreted as showing muscle enhancement. Of the 26 breasts which did not demonstrate muscle enhancement, none were found at surgery to have tumor involvement. CONCLUSION: Enhancement of the pectoralis muscle correlates well with muscle invasion, but there are a few potential pitfalls. Disruption of the fat plane between tumor and muscle, without muscle enhancement, might not indicate tumor involvement of the pectoralis muscle.     

A case of locally recurrent breast cancer in which phlebothrombosis of the right leg after hormonal therapy using a high dose of toremifene citrate

A 72-year-old female had undergone mastectomy at the age of 67 for right breast cancer (T2a, n1 alpha, positive for ER). In the surgery the pectoralis muscle was preserved. For adjuvant therapy, 20 mg/day of tamoxifen was orally administered for 5 years. Six years after surgery, relapse was detected in the right major pectoralis muscle. Irradiation at this site and oral administration of 120 mg/day of toremifene citrate were started. The patient had a medical history of diabetes, and the control of her blood sugar was poor. About 2 months after oral administration of toremifene citrate was started, flares with blebs and swelling were observed in the right lower leg, suggesting acute phlebothrombosis of the right lower limb. The symptoms were ameliorated by intravenous administration of heparin and an antibiotic. In administering a high dose of toremifene citrate to patients with complications, careful follow-up is needed.     

Sentinel node biopsy in breast cancer patients with clinically negative lymph-nodes

Background  The purpose of the present study is to evaluate the usefulness of dye-guided sentinel node biopsy in breast cancer patients with clinically negative nodes and to clarify the anatomic distribution of sentinel nodes in the axilla. Methods  Sentinel node biopsy was performed in patients with T1 or T2 breast cancer who had clinically negative nodes, using an indocyanin green dye-guided method. Thereafter, complete axillary dissection was performed. Sentinel node and complete axillary lymph-node dissection specimens were examined separately, and the incidence of metastases was compared. Results  We identified sentinel nodes in 115 (76.7%) of 150 patients with clinically negative nodes. The mean number of sentinel nodes was 1.7 (range, one to eight nodes). The mean size of sentinel nodes was 9.0 mm (range, 2.0 to 28.0 mm). Of the 31 patients who had a tumor-positive sentinel node, 14 (45.2%) patients had only the sentinel node involved. There was concordance on histological examination between sentinel node and axillary node status in 111 (96.5%) of 115 cases. Of the sentinel nodes 89.1% were located cranially to the intercostobrachial nerve and within 2 cm of the lateral edge of the pectoralis minor muscle. Conclusions  Sentinel node biopsy guided by indocyanin green dye is an easy technique with an acceptable detection rate of sentinel nodes for breast cancer patients with clinically negative nodes. Most of the sentinel nodes were located near the lateral edge of the pectoralis minor muscle and cranial to the intercostobrachial nerve.

Interpectoral nodes in carcinoma of the breast: Requiem or resurrection

Fifty-eight consecutive patients undergoing a modified radical mastectomy were subjected to complete dissection and pathological assessment of the interpectoral fascia and the group of lymph nodes it contains. The dissection was carried out in all patients, irrespective of whether they were palpable or not. Interpectoral nodes (IPNs) were anatomically present in 28 patients (48%) and were completely absent in 30 patients (52%). Ten patients were Stage I, 18 were Stage II, and 30 were Stage III. Of the 25% (15/58) of patients with microscopic metastasis, only 12/15 had palpable nodes; 66% (10/15) of patients had axillary and apical nodes positive. Significantly, two patients with negative nodes in the axillary and apical group had metastatic Rotter's nodes. Of the 15 patients with positive IPNs, nine had primary tumors located within the upper quadrants of the breast, whereas only five had tumors in lower quadrants and one had a centrally located tumor. The neurovascular bundle to the pectoralis major could be safely preserved in 93% (54/58) of patients. The incidence of impalpable nodes with microscopic metastasis and the evidence of exclusively metastatic interpectoral nodes with uninvolved axillary and apical nodes prompt the following conclusions: (1) interpectoral fascia and nodes should be mandatorily dissected in all patients irrespective of the nodes being palpable or not; (2) the dissection is anatomic and is associated with almost no additional morbidity; (3) the group of patients with IPNs positive and the axillary group negative, would benefit maximally from the IPN dissection. Similarly, this dissection in all other groups of patients would enable a more accurate staging and selection of therapeutic strategies. © 1996 Wiley-Liss, Inc.     

Use of the lateral portion of the pectoralis major muscle to cover exposed axillary structures

The pectoralis major myocutaneous flap has been used to cover many different defects. This article will describe the use of the lateral portion of the pectoralis major muscle to cover exposed axillary structures when the latissimus dorsi muscle is not available for coverage.
