Intraoperative Identification of the Parathyroid Gland with a Fluorescence Detection System.

BACKGROUND: Intraoperative identification of the difficult-to-spot parathyroid gland is critical during surgery for thyroid and parathyroid disease. Recently, intrinsic fluorescence of the parathyroid gland was identified, and a new method was developed for intraoperative detection of the parathyroid with an original fluorescent detection apparatus. Here, we describe a method for intraoperative detection of the parathyroid using a ready-made photodynamic eye (PDE) system without any fluorescent dye or contrast agents. METHODS: Seventeen patients who underwent surgical treatment for thyroid or parathyroid disease at Kagoshima University Hospital were enrolled in this study. Intrinsic fluorescence of various tissues was detected with the PDE system. Intraoperative in vivo and ex vivo intrinsic fluorescence of the parathyroid, thyroid, lymph nodes and fat tissues was measured and analyzed. RESULTS: The parathyroid gland had a significantly higher fluorescence intensity than the other tissues, including the thyroid glands, lymph nodes and fat tissues, and we could identify them during surgery using the fluorescence-guided method. Our method could be applicable for two intraoperative clinical procedures: ex vivo tissue identification of parathyroid tissue and in vivo identification of the location of the parathyroid gland, including ectopic glands. CONCLUSION: The PDE system may be an easy and highly feasible method to identify the parathyroid gland during surgery.

The clinical usefulness of the intraoperative detection of sentinel lymph node metastases by a rapid RT-PCR system in patients with gastric cancer.

BACKGROUND: The incidence of pathological lymph node metastases in patients with gastric cancer is 5% to 10%, which means that approximately 90% of patients with gastric cancer may undergo unnecessary lymphadenectomy. The precise intraoperative diagnosis of sentinel lymph node (SN) metastases is essential. The purpose of the current study was to verify the usefulness of a rapid reverse transcriptase-polymerase chain reaction (RT-PCR) system compared with hematoxylin and eosin staining for such diagnoses. METHODS: A total of 113 patients with clinical T1-T2 (cT1-T2) gastric cancer, including 73 patients with cT1cN0 disease with a tumor diameter <4 cm, were enrolled in the current study. SNs were identified by a radioisotope method. Carcinoembryonic antigen and cytokeratin 19 were used as markers for RT-PCR and the cutoff values were set using 1701 lymph nodes harvested from 157 patients with gastric cancer. RESULTS: SNs were detected in all 113 patients. Sensitivity and accuracy for detection by paraffin section were both 100% in patients with cT1 disease and were 60% and 90%, respectively, in patients with cT2 disease. The sensitivity of RT-PCR for the detection of pathological SN metastases was 92.3%. Furthermore, 11 patients had SN metastases detected only by RT-PCR, and these patients had frequent lymphatic invasion. Hematoxylin and eosin staining detected SN metastases in 6 of 73 patients with cT1cN0 gastric cancer; RT-PCR and frozen section detected SN metastases in 6 and 4 of these patients, respectively. Accordingly, the sensitivity of RT-PCR and frozen section for the detection of those pathological SN metastases were 100% and 66.6%, respectively. CONCLUSIONS: The rapid RT-PCR system appears to have clinical usefulness for the intraoperative detection of SN metastases in patients with gastric cancer.

Therapeutic mammoplasty combining partial mastectomy with nipple-areola grafting for patients with early breast cancer: a case series.

PURPOSE: Therapeutic mammoplasty (TM) for breast cancer is a widely practiced oncoplastic technique. Intraductal spread towards the nipple or the location of the cancerous lesion on the central breast may become a contraindication for breast-conserving surgery. We herein report the results of TM in such cases. METHODS: Six patients underwent TM that combined partial mastectomy with free nipple-areola (NA) grafting. The nipple was removed together with the cancerous lesions, and the areola was preserved for NA reconstruction. The tumors were located in the lower quadrant (n = 1), the central area (n = 1), the upper-outer area (n = 2), and the upper-inner area (n = 2). The types of mammoplasty that were performed included: amputation (n = 1), inverted T mammoplasty (n = 3), and L mammoplasty (n = 2). With the exception of one patient, all patients underwent inverted T mammoplasty on the contralateral breast in order to achieve symmetry. RESULTS: The total surgical and plastic periods ranged from 155 to 235 min (mean 207 min) and 100 to 150 min (mean 121 min), respectively. Oncological safety and excellent cosmetic results were achieved. CONCLUSIONS: TM combining partial mastectomy with NA grafting was successfully performed in patients with early-stage cancer in all quadrant areas.

Clinical Significance of Circulating Tumor Cells in Peripheral Blood of Patients with Esophageal Squamous Cell Carcinoma.

BACKGROUND: Esophageal squamous cell carcinoma is an aggressive gastrointestinal tract cancer. To date, the presence of circulating tumor cells (CTC) has been reported as a prognostic factor in peripheral blood from patients with gastrointestinal cancers. METHODS: The CellSearch system was used to isolate and enumerate CTCs. A total of 90 patients with esophageal squamous cell carcinoma who received chemotherapy or chemoradiotherapy were enrolled. Peripheral blood specimens were collected before and after treatments. RESULTS: At baseline analysis, CTCs were detected in 25 patients (27.8 %). Overall survival was significantly shorter in patients with than without CTCs. Follow-up blood specimens were obtained from 71 patients. Partial response, stable disease, and progressive disease after treatment were seen in 32, 12, and 27 patients, respectively. CTC positivity after treatment in the progressive disease group (40.7 %) was significantly higher than that of the partial response group (6.3 %). Patients with a change in CTC status from positive to negative had a good prognosis as well as patients without baseline CTCs. CONCLUSIONS: Evaluation of CTCs may be a promising indicator for predicting tumor prognosis and the clinical efficacy of chemotherapy or chemoradiation therapy in patients with esophageal squamous cell carcinoma.

Impaired wound healing and expansion of a large ulcer after bevacizumab with paclitaxel for skin metastases from breast cancer: report of a case.

A 48-year-old Japanese woman was found to have local recurrence of breast cancer in the chest wall following neoadjuvant chemotherapy, total mastectomy with axillary lymphadenectomy, postoperative radiation therapy to the chest wall, and adjuvant systemic therapy using trastuzumab. As a third line of treatment after recurrence, bevacizumab with paclitaxel was initiated for several metastatic lesions on the skin of the chest wall, left internal costal lymph nodes, and right axillary lymph nodes. The wound on the chest wall continued to expand in diameter and depth after the third course of bevacizumab with paclitaxel until the rib was exposed. After stopping the bevacizumab, granulation tissue expanded and by 3 months, had covered the bottom of the ulcer. The patient died soon thereafter, despite systemic chemotherapy with eribulin; however, there was no further bleeding from the ulcer on the chest wall or the exposed ribs.

Computed tomography Hounsfield units can predict breast cancer metastasis to axillary lymph nodes.

BACKGROUND: Axillary lymph node (ALN) status is an important prognostic factor for breast cancer. We retrospectively used contrast-enhanced computed tomography (CE-CT) to evaluate the presence of ALN, metastasis based on size, shape, and contrasting effects. METHODS: Of 131 consecutive patients who underwent CE-CT followed by surgery for breast cancer between 2005 and 2012 in our institution, 49 were histologically diagnosed with lymph node metastasis. Maximum Hounsfield units (HU) and mean HU were measured in non-contrasting CT (NC-CT) and CE-CT of ALNs. RESULTS: Of 12 examined measurements, we found significant differences between negative and metastatic ALNs in mean and maximum NC-CT HU, and mean and maximum CE-CT HU (P < 0.05). We used a receiver operating curve, to determine cut-off values of four items in which significant differences were observed. The highest accuracy rate was noted for the cut-off value of 54 as maximum NC-CT HU for which sensitivity, specificity, and accuracy rate were 79.6%, 80.5% and 80.2%, respectively. CONCLUSIONS: CT HU of a patient with breast cancer are absolute values that offer objective disease management data that are not influenced by the screener's ability.

Oncoplastic breast surgery combining partial mastectomy with immediate breast reshaping using a keyhole-shaped skin glandular flap for Paget's disease.

Oncoplastic breast surgery (OBS), which combines the concepts of oncologic and plastic surgery, is becoming more common worldwide. We herein report the results of OBS in Japanese patients with Paget's disease. We performed OBS combining partial mastectomy with immediate breast reshaping using a keyhole-shaped skin glandular flap in two patients. In these two patients, who were diagnosed as having Paget's disease with a restricted intraductal component in the central area of their non-ptotic breast, we performed oncoplastic surgery combining partial mastectomy with immediate breast reshaping using a keyhole-shaped skin glandular flap. Neither of the two patients received contralateral surgery to produce symmetrical breasts. The observation period ranged from 6 to 12 months, and the bilateral breast volumes and inframammary lines were symmetric. OBS combining partial mastectomy with immediate breast reshaping using a keyhole-shaped skin glandular flap was successfully performed in two patients with Paget's disease.

Oncoplastic surgery combining partial mastectomy and immediate volume replacement using a thoracodorsal adipofascial cutaneous flap with a crescent-shaped dermis.

PURPOSE: The treatment of early breast cancer using breast-conserving therapy commonly ensures local control and acceptable cosmetic results. We herein report a useful technique, including the use of a thoracodorsal adipofascial cutaneous flap for reconstructing defects in the outer quadrant area after partial mastectomy, which achieved excellent results. METHODS: We performed partial mastectomy followed by immediate volume replacement using a modified thoracodorsal adipofascial cutaneous flap with a crescent-shaped dermis in ten patients. RESULTS: The modified oncoplastic technique was performed without any complications in all patients. Sufficient blood flow to the cutaneous flap with the crescent-shaped dermis was visualized in two patients during the operation after the injection of indocyanine green. The oncological and cosmetic results were excellent to good in these patients. CONCLUSIONS: Oncoplastic surgery using a modified thoracodorsal adipofascial flap with a crescent-shaped dermis was successfully performed in patients with early cancer lesions in the outer quadrant, and the cosmetic results obtained were excellent.

Clinical significance of circulating tumor cells in peripheral blood from patients with gastric cancer.

BACKGROUND: The authors hypothesized that circulating tumor cells (CTCs) in patients with gastric cancer are associated with prognosis and disease recurrence. In this study, they evaluated CTCs in gastric cancer and clarified the clinical impact of CTCs. METHODS: In total, 265 consecutive patients with gastric cancer were enrolled. Fourteen patients were excluded from the analysis, including 12 patients who another cancer and 2 patients who refused the treatment. The remaining 251 patients were divided into 2 groups: 148 patients who underwent gastrectomy (the resection group) and 103 patients who did not undergo gastrectomy (the nonresectable group). Peripheral blood samples were collected before gastrectomy or chemotherapy. A proprietary test for capturing, identifying, and counting CTCs in blood was used for the isolation and enumeration of CTCs. RESULTS: CTCs were detected in 16 patients (10.8%) from the resection group and in 62 patients (60.2%) from the nonresectable group. The overall survival rate for the entire cohort was significantly lower in patients with CTCs than in those without CTCs (P < .0001). In the resection group, relapse-free and overall survival in patients with CTCs was significantly lower than in patients without CTCs (P < .0001). It was noteworthy that the expression of CTCs was an independent factor for determining the overall survival of patients with gastric cancer in multivariate analysis (P = .024). In the nonresectable group, the overall survival rate was significantly lower in patients with CTCs than in those without CTCs (P = .0044). CONCLUSIONS: The evaluation of CTCs in peripheral blood may be a useful tool for predicting tumor progression, prognosis, and the effect of chemotherapy in patients with gastric cancer.

Assessment of sentinel node concept in esophageal cancer based on lymph node micrometastasis.

PURPOSE: The clinical significance of lymph node micrometastasis remains unclear in patients with esophageal cancer. Therefore, accurate assessment of lymph node status including micrometastasis is important when performing sentinel node (SN) navigation surgery. The purpose of the present study was to investigate the adequacy of SN concept based on lymph node micrometastasis determined by immunohistochemistry (IHC) and reverse transcription-polymerase chain reaction (RT-PCR) in patients with esophageal cancer. METHODS: A total of 57 patients with esophageal cancer who were preoperatively diagnosed as having T1-T2 (cT1-T2) and N0 (cN0) were enrolled. They underwent standard esophagectomy with lymph node dissection. One day before surgery, a total of 3 mCi of 99mTechnetium-tin colloid was endoscopically injected into the submucosa around the tumor. During the operation, radioisotope uptake in the lymph nodes was measured using Navigator GPS. All dissected lymph nodes were investigated by RT-PCR using the double marker of CEA and SCC, hematoxylin-eosin (HE) staining, and IHC. RESULTS: Node-positive incidence identified by HE and IHC was 12.3% (7/57) and 19.3% (11/57), respectively. RT-PCR demonstrated micrometastasis in four of 46 patients without nodal metastasis determined by HE staining and IHC. No non-SN metastases were found in 42 patients without micrometastasis identified by IHC and RT-PCR of SN. Accuracy and false negative rates were 100% (57/57) and 0% (0/42), respectively. CONCLUSIONS: SN concept might be acceptable in patients with cT1-T2 and cN0 esophageal cancer, even in the presence of micrometastasis identified by IHC and RT-PCR.

Feasibility of sentinel node navigation surgery after noncurative endoscopic resection for early gastric cancer.

BACKGROUND AND AIM: Recently, the use of additional surgery after noncurative endoscopic resection has gradually increased due to the rapid spread of endoscopic treatments in selected patients with early gastric cancer. Sentinel node navigation surgery (SNNS) has also been recognized as a minimally invasive surgery with personalized lymphadenectomy in early gastric cancer. Here, we assessed the feasibility of SNNS after noncurative endoscopic resection for early gastric cancer. METHODS: Sixteen patients with early gastric cancer, in whom additional surgery had been indicated due to noncurative endoscopic resection, were enrolled. They underwent a gastrectomy with standard lymphadenectomy. One day before surgery, (99m) technetium-tin colloid was endoscopically injected into the submucosa around the tumor. After surgery, the uptake of radioisotope in dissected lymph nodes was measured using Navigator GPS. Then, all dissected lymph nodes were investigated by hematoxylin-eosin staining and immunohistochemistry using an antihuman cytokeratin monoclonal antibody. RESULTS: Hematoxylin-eosin staining demonstrated lymph node metastasis in two (12.5%) of 16 patients and in three (0.8%) of 382 nodes. However, immunohistochemistry showed that none of the patients had lymph node micrometastasis. Sentinel nodes (SNs) were identified in all patients. The mean number of SNs was 3.1 (range, 1-6). Among two patients with lymph node metastasis, the SNs, at least, contained positive nodes. Accordingly, the false-negative and accuracy rates were 0% and 100%, respectively. CONCLUSION: Our results indicate that SNNS may have potential as a further minimally invasive surgery in early gastric cancer patients after noncurative endoscopic resection.

Trans-Oral Video-Assisted Neck Surgery (TOVANS). A new transoral technique of endoscopic thyroidectomy with gasless premandible approach.

BACKGROUND: Endoscopic thyroidectomy is a well-established surgical technique. We have been utilizing precordial video-assisted neck surgery (VANS) with a gasless anterior neck skin lifting method. Recently, natural orifice transluminal endoscopic surgery (NOTES) has generated excitement among surgeons as potentially scar-free surgery. We developed an innovative gasless transoral technique for endoscopic thyroidectomy that incorporated the concept of NOTES in a VANS-technique. METHODS: Incision was made at the vestibulum under the inferior lip. From the vestibulum to the anterior cervical region, a subplatysmal tunnel in front of the mandible was created and cervical skin was lifted by Kirschner wires and a mechanical retracting system. This method without CO2 insufflation created an effective working space and provided an excellent cranio-caudal view so that we could perform thyroidectomy and central node dissection safely. RESULTS: Beginning with our first clinical application of TOVANS in September 2009, we have performed eight such procedures. Three of the eight patients had papillary microcarcinoma and received central node dissection after thyroidectomy. All patients began oral intake 1 day after surgery. The sensory disorder around the chin persisted more than 6 months after surgery in all patients. Recurrent laryngeal nerve palsy revealed in one patient. Nobody had mental nerve palsy, and no infection developed with use of preventive antibacterial tablets for 3 days. CONCLUSIONS: We developed a new method for gasless transoral endoscopic thyroidectomy with a premandible approach and anterior neck-skin lifting. TOVANS makes possible complete endoscopic radical lymphadenectomy for papillary thyroid cancer. We believe that this method is innovative and progressive and has not only a cosmetic advantage but also provides easy access to the central node compartment for dissection in endoscopic thyroid cancer surgery.

Oncoplastic breast surgery combining periareolar mammoplasty with volume displacement using a crescent-shaped cutaneous flap for early breast cancer in the upper quadrant.

Oncoplastic breast surgery (OBS), which combines the concepts of oncological and plastic surgery, is becoming more common, especially in Western countries; however, only a few reports have been published in Japan. We herein report the results of OBS for Japanese patients with early breast cancer in the upper quadrant. We performed oncoplastic surgery combining partial mastectomy using a periareolar incision with immediate breast reshaping using a crescent-shaped cutaneous flap in three patients with a past history of breast-feeding, ptotic breasts and lesions that were suitable for breast conserving surgery. The lesions were located in the upper quadrant and were 5, 6 and 10 cm from the nipple, respectively. The total length of the operations ranged between 86 and 192 min, with the mean being 164 min. Two patients underwent contralateral surgery to produce symmetrical breasts and one did not. The plastic period after receiving pathological results intraoperatively ranged between 47 and 120 min, with the mean period being 82 min. The observation period ranged between 6 and 12 months, and the cosmetic results were excellent in all three cases. OBS combining partial mastectomy using a periareolar incision with immediate breast reshaping using a crescent-shaped cutaneous flap was successfully performed in patients with early cancer in the upper quadrant.

Immediate reconstruction using a modified inframammary adipofascial flap after partial mastectomy.

Breast conservative therapy (BCT) as treatment for early breast cancer usually ensures local control and acceptable cosmetic results. We describe a new technique of using an inframammary adipofascial flap to reconstruct defects caused by lower-pole partial mastectomy, which achieved excellent results (Kijima et al. in Am J Surg 193:789-91 (1); Sakai et al. in Ann Plast Surg 29(2):173-7, 2; Ogawa Am J Surg 193:514-8, 3). We developed this procedure as an oncoplastic technique for a Japanese woman with a similar defect without ptosis. After partial mastectomy, the superior half of the flap is harvested via an initial incision along the inframammary line, and the inferior half is harvested via an additional incision along the caudal edge of the flap, to produce a crescent of de-epithelialized skin. A tongue-shaped flap containing the crescent of de-epithelialized skin, subcutaneous fat, and the fascia of the vertical rectus abdominis muscle is then rotated upwards, gathered, and inserted into the breast defect.

Sentinel node navigation surgery is acceptable for clinical T1 and N0 esophageal cancer.

BACKGROUND: If the sentinel node (SN) concept is established for esophageal cancer, it will be possible to reduce safely the extent of lymphadenectomy. Our objective was to perform SN mapping in esophageal cancer to assess distribution of lymph node metastases with the goal to reduce the need for extensive lymphadenectomy. METHODS: A total of 134 patients who underwent esophagectomy with lymph node dissection were enrolled. The number of patients with clinical T1, T2, and T3 tumors was 60, 31, and 32, respectively. Eleven patients also received neoadjuvant chemoradiation therapy (CRT). (99m)Tc-Tin colloid was injected endoscopically into the esophageal wall around the tumor 1 day before surgery. SNs were identified by using radioisotope (RI) uptake. RI uptake of all dissected lymph nodes was measured during and after surgery. Lymph node metastases, including micrometastases, were confirmed by hematoxylin eosin and immunohistochemical staining. RESULTS: Detection rates of SNs were 93.3% in cT1, 100% in cT2, 87.5% in cT3, and 45.5% in CRT patients. In the 120 cases where SNs were identified, lymph node metastases were found in 12 patients with cT1, 18 with cT2, 24 with cT3 tumors, and 3 with CRT. Accuracy rate of SN mapping was 98.2% in cT1, 80.6% in cT2, 60.7% in cT3, and 40% in CRT patients. Although one false-negative case had cT1 tumor, the lymph node metastasis was detected preoperatively. CONCLUSIONS: SN mapping can be applied to patients with cT1 and cN0 esophageal cancer. SN concept might enable to perform less invasive surgery with reduction of lymphadenectomy.

Prognostic impact of CD168 expression in gastric cancer.

BACKGROUND: Interactions of stromal hyaluronic acid (HA) with its binding protein RHAMM (receptor for HA-mediated motility) (CD168) have been reported to affect tumor extension and the migration of crucial molecules to promote tumor progression and metastases. Cancerous CD168 expression is correlated with aggressive biological features in several cancers. However, the clinical implications of CD168 positivity in gastric cancer have remained unclear. METHODS: We examined the CD168 expression of 196 consecutive gastric cancer patients by immunohistochemistry. According to CD168 positivity, the 196 gastric cancer patients were divided into two groups (57 CD168-positive and 139 CD168-negative patients). The correlation between CD168 expression and clinicopathological factors (age, sex, histology, tumor depth, lymph node status, and vessel invasion) was evaluated according to the Japanese Classification of Gastric Carcinoma. RESULTS: Cancerous CD168 expression was detectable in 57 of the 196 tumors (29%). CD168 positivity was significantly correlated with the depth of invasion, nodal involvement, and vessel invasion (p < 0.01). Survival analysis of the 196 gastric cancer patients showed that the CD168-positive group had a significantly higher mortality than the CD168-negative group (p < 0.01). In terms of a correlation with CD168 positivity at separate clinical stages, a significance difference was only found in stages II and III. Multivariate analysis revealed that CD168 expression was a significant independent prognostic marker (p = 0.013) after depth of invasion (p < 0.005) and nodal involvement (p < 0.01). CONCLUSION: Our results suggest that cancerous CD168 positivity is strongly related to the invasion and metastasis of gastric cancer tumors. These results suggest that cancerous CD168 expression can be used as a prognostic marker of gastric cancer owing to its interactions with stromal hyaluronic acid.

Clinical implication of CD166 expression in gastric cancer.

BACKGROUND: CD166 is one of the cell-surface immunoglobulins, and is well known to regulate leukocyte mobility. Its expression is associated with aggressive tumor behavior. CD166 expression is a prognostic marker in several cancers, but the predictive value of CD166 expression in gastric cancer has not been clarified yet. PATIENTS AND METHODS: A total of 142 gastric cancer patients who consecutively received curative gastrectomy in Kagoshima University Hospital were enrolled in the current study. The patients were composed of 99 men and 43 women, ranging in age from 42 to 84 years (mean 63 years). Cancerous CD166 expression was evaluated immunohistochemically. RESULTS: Cancerous CD166 expression was identified in not only cellular membrane but also cytoplasm. The rates of membranous and cytoplasmic CD166 positivities were 25.4% and 34.4%, respectively. Cytoplasmic and membranous CD166 positivities were significantly correlated with nodal involvement and vascular invasion. Survival analysis of the 142 gastric cancer patients revealed that membranous CD166-positive group (median survival 18.6 months, range 0.3-104.5 months) had a significantly poorer outcome than CD166-negative group (median 25.7 months range 1.4-106 months) (P < 0.05). CONCLUSIONS: Membranous CD166-positivity may contribute to one of the promising prognostic markers in gastric cancer.

Oncoplastic surgery combining partial mastectomy with breast reconstruction using a free nipple-areola graft for ductal carcinoma in situ in a ptotic breast: report of a case.

We report a case of early breast cancer, which was treated successfully by oncoplastic surgery. A 65-year-old Japanese woman was referred to us for investigation of a grouped calcification on mammography of her left breast, detected during mass screening for breast cancer. No mass lesion was palpated, but we suspected that the grouped calcification seen on the mammography was a malignant lesion in the lower area of the left breast. Ultrasonography and magnetic resonance imaging revealed ductal carcinoma in situ, restricted to the inner quadrant of the left breast. Achieving a good symmetrical outcome after partial mastectomy would have been made difficult by the degree of ptosis. Thus, we performed partial mastectomy followed by an amputation-type reduction operation with free nipple-areola complex grafting, which achieved good cosmetic and oncologic results.

Immediate breast reconstruction using autologous free dermal fat grafts provides better cosmetic results for patients with upper inner cancerous lesions.

PURPOSE: Although breast-conserving therapy (BCT) is the standard form of treatment for early-stage breast cancer, in patients with small breasts cosmetic results can be poor, especially when the lesion is located on the inner upper quadrant area. This study analyzes our use of autologous free dermal fat grafts (FDFGs) for immediate breast reconstruction. METHODS: A total of 23 patients who received a partial mastectomy for an inner upper quadrant lesion from 1992 to 2006 at Kagoshima University Hospital were retrospectively divided into three groups according to the reconstructive procedure that was used for the defect after partial mastectomy: immediate reconstruction using an autologous FDFG from the lower abdomen (group FDFG); patients receiving only rotation and fixation of the parenchymal adipose tissue or gland to repair the defect (group GL); and a third group who underwent immediate reconstruction using a miniflap of the latissimus dorsi (group LD). RESULTS: The total duration of surgery in group FDFG was significantly shorter than in group LD (P < 0.01). The mean volume of blood lost in group FDFG was significantly lower than in group LD (P < 0.01). The breast retraction assessment (BRA) of group FDFG was significantly better than for the patients in groups GL and LD (P < 0.01). The total score using the ABNSW system for cosmetic assessment was significantly better in group FDFG than in group GL (P < 0.01). Similarly, the total score in group FDFG using the assessment by the Japanese Breast Cancer Society was significantly higher than that in group GL (P < 0.01). CONCLUSION: Immediate breast reconstruction for a defect after a partial mastectomy of an upper inner quadrant malignant lesion using FDFG can be especially useful for patients with small breasts.

Oncoplastic surgery for Japanese patients with breast cancer of the lower pole.

This report presents the results of oncoplastic surgery in three Japanese patients with breast cancer lesions involving the lower pole of the breast. Their breasts were ptotic, and their lesions were considered to be suitable for breast conservation surgery. There were treated with partial mastectomy resection using vertical-scar mammaplasty, with reduction surgery and recentralization of the nipple-areola complex. Two patients underwent a mirror-image biopsy on the contralateral breasts to determine the symmetry. The remaining patient had periareolar incision mastopexy without reduction added for the contralateral breast. A large surgical margin was used to remove excessive skin and parenchymal tissue. Ideal symmetry was achieved by performing reduction and/or mastopexy on the contralateral breast.
