Metastatic pheochromocytoma to liver without elevation of metanephrines and catecholamines

IntroductionMalignant pheochromocytoma represents 10% of all patients with pheochromocytoma. Of these cases, only 5–9% presents without elevation of metanephrines and catecholamines.Presentation of caseA 43-year-old female patient presented with an abdominal tumor. An exploratory laparotomy was performed and the final report was a pheochromocytoma. After ten years, multiple liver lesions were detected and surgical treatment was performed. Pathological evaluation revealed a malignant pheochromocytoma with negative margins after 5 years of follow-up without evidence of disease.DiscussionThe recurrence rate of malignant pheochromocytoma is 15–20% at ten years and a 5-year survival rate that ranges from 50% to 80%. The presence of synchronous metastases is rare (10–27%), but have been reported until 20 years later with the most common metastatic sites being the local lymph nodes, bone (50%), liver (50%) and lung (30%). The prognostic factor such as size >6 cm, age over 45 years, synchronous metastasis and no tumor excision are related with poor prognosis.ConclusionSurgical treatment offers the best survival rate and the only chance of cure so far and the goal is an R0 resection as in our case. So it should be the treatment of choice.     

Results of laparoscopic adrenalectomy for suspected and unsuspected malignant adrenal neoplasms

BACKGROUND: Laparoscopic resection for malignant adrenal tumors is controversial, because they are rare and limited data exist in the literature. HYPOTHESIS: Laparoscopic adrenalectomy for malignant adrenal tumors is safe and effective. PATIENTS AND METHODS: Twenty-three patients who had a laparoscopic approach for suspected and unsuspected malignant adrenal tumors were studied retrospectively. The adrenal mass was suspected to be metastatic if the patient had a history of previous extra-adrenal primary malignancy and/or positive fine-needle aspiration cytologic findings. A primary adrenal cancer was suspected if there were positive fine-needle aspiration cytologic findings and/or a malignant adrenal imaging phenotype. MAIN OUTCOME MEASURES: (1) Margins of tumor resection, (2) tumor recurrence (locoregional, port site, and distant), and (3) disease-free survival. RESULTS: Twenty-three patients (15 men and 8 women) had 24 laparoscopic procedures (20 adrenalectomies, 3 biopsies, and 1 diagnostic laparoscopy). Permanent histologic specimens in the 23 patients showed 5 adrenocortical cancers, 1 undifferentiated adrenal cancer, 13 adrenal metastases, 2 lymphomas, and 2 cases with no evidence of tumor. Clinically suspected adrenal metastases were true positive in 19 patients (83%). The sensitivity of fine-needle aspiration cytology was 57% (n = 7). Only 1 of 6 patients with primary adrenal cancer was suspected to have a malignant tumor preoperatively. The tumor resection margin was negative in all adrenalectomies. There were 3 locoregional recurrences (2 local and 1 lymph node metastasis) in the 6 patients with primary adrenal cancer, no port site recurrences, and 4 distant recurrences in 13 patients with metastatic adrenal tumors. The disease-free survival was 65% at a mean follow-up time of 3.3 years (range, 1-7 years). CONCLUSIONS: A laparoscopic approach in patients with suspected adrenal metastasis can be both diagnostic and therapeutic, and achieves complete tumor resection. In contrast, laparoscopic adrenalectomy for clinically unsuspected adrenocortical cancer is associated with a high recurrence rate. Furthermore, preoperative fine-needle aspiration cytology for the evaluation of suspected malignant adrenal tumors is unreliable.     

Breast carcinoma metastasis to meningioma in the thoracic spine: A case report and review of the literature

Abstract

Context

Systemic metastasis to a primary tumor of the central nervous system is uncommon. Breast carcinomas metastasizing to a possibly preexisting meningioma in the spine are reported very rarely.

Study design

Case report.

Findings

A 69-year-old female was referred to us with progressive gait disturbance. She had undergone a total mastectomy for carcinoma of the right breast 11 years previously. A magnetic resonance imaging of the thoracic spine showed an intra- and extradural spinal cord tumor. The patient underwent resection of the tumor via laminectomy from T2 to T4. After the operation, the patient's neurological status improved significantly, and she was able to walk without assistance. Histological examination showed the tumor to be a fibrous-type meningioma within a metastatic breast cancer tumor. The patient underwent 40 Gy radiation treatment for local control of the tumor. However, the tumor recurred locally 7 months after the surgery. The patient died of carcinomatous pleurisy 13 months after the surgery.

Conclusion

This case illustrates that a primary meningioma in the thoracic spine can be a recipient of breast cancer metastasis, which may alter the treatment strategy.     

Adrenal metastasis of a phyllodes tumor of the breast: Case report and review of the literature

INTRODUCTIONA phyllodes tumor is a neoplasm of mixed mesenchymal and epithelial origin affecting the breast. It may pursue a benign or malignant evolution with distant metastases in the latter case. Sites most commonly affected by metastases are the lungs and bones. Simple mastectomy is the mainstay of treatment. This article presents the first described case of metastasis to the adrenal gland after sarcomatous transformation of a phyllodes tumor. A review of the literature is presented afterwards.PRESENTATION OF CASEA 57-year old female patient presented with a voluminous breast mass which was completely resected. Unfortunately she presented with malignant recurrence in the breast which was also resected. A later recurrence within the lung presented and was completely resected but showed aspects of sarcomatous changes. Finally a recurrence was pathologically documented within the adrenal gland. Unfortunately, disease later progressed and the patient refused further treatment at that point.DISCUSSIONWhile malignant transformation of breast phyllodes tumors and metastasis is relatively common, the prognosis for initially benign lesion that are completely excised is usually good. This case represents the first documented metastasis to the adrenal gland of a breast phyllodes tumor.CONCLUSIONWe presented the first case of adrenal metastasis of a phyllodes tumor after sarcomatous degeneration. This is an unusual presentation of a relatively uncommon but well-recognized disease of variable malignant potential.     

Case report: Successful treatment of recurrent chordoma and bilateral pulmonary metastases following an 11-year disease-free period

INTRODUCTION

Chordomas are rare but aggressive tumors due to local recurrence and distant metastases. They originate commonly in the sphenooccipital and sacrococcygeal regions, and metastasize to the lungs, bone, skin, liver, and lymph nodes. They occur more frequently in men and people over the age of 40.

PRESENTATION OF CASE

A 28 year-old female presented with sacrococcygeal chordoma for which she received wide local excision and adjuvant radiation therapy. She enjoyed an unusual disease-free survival for 11 years until a routine surveillance scan of the pelvis identified local recurrence. Further work up revealed bilateral pulmonary metastases. She underwent local excision of the recurrent tumor and video-assisted thoracoscopic (VATS) wedge resection of pulmonary metastases. She also received adjuvant radiation therapy to the recurrent resection bed. Two years later, she remains free of disease and symptoms.

DISCUSSION

Chordomas are commonly insensitive to chemotherapy and radiation, making surgery the most successful therapeutic modality. However, there are few guidelines on the surveillance and treatment of recurrent chordoma. We report success with aggressive surgical resection of recurrence and metastasis as well as adjuvant radiation therapy.

CONCLUSION

The prolonged survival of our patient underscores the importance of (1) aggressive surgical resection of chordoma, whether primary, recurrent, or metastatic, with adjuvant radiation therapy, (2) minimization of surgical seeding of tumor, and (3) diligent cancer surveillance.     

How far should we treat metastatic liver cancer? Report of three long-term survivors

The major issue in treating metastatic liver cancer is: how far should we perform resection? We believe that only reports of long-term survival afford an answer to this problem. We report three such patients. The first patient underwent pancreatoduodenectomy for cancer of the papilla of the duodenum and resection of metastatic liver cancer. She is alive without recurrence 15 years and 1 month after the initial surgery. The second patient received low anterior resection for rectal cancer, extended right lobectomy for liver metastasis, and pancreatoduodenectomy for metastasis at the common bile duct. She survived 6 years and 9 months after the initial surgery. The third patient underwent right nephrectomy for Wilms' tumor (adult type), extended right lobectomy for liver metastasis, and repeat resection of recurrences at the mediastinum and in the thoracic and abdominal walls. She is alive 21 years and 2 months after the initial surgery. These experiences have prompted us to carry out resection when surgery is deemed feasible.     

Treatment of colorectal liver metastasis with biliary and portal vein tumor thrombi by hepatopancreatoduodenectomy

We present a case of a large colorectal liver metastasis with portal vein and biliary tumor thrombi and duodenal and jejunal direct invasion that required hepatopancreatoduodenectomy. A 38-year-old woman presented to her local hospital with right back pain and jaundice. She had undergone transverse colectomy and limited liver resection for transverse colon cancer with a synchronous liver metastasis in September 1991, and low anterior resection for rectal carcinoma in January 1996. She was diagnosed as having colorectal liver metastasis and was referred to our hospital for possible surgery. Radiologic and endoscopic examinations revealed a large liver tumor occupying the right lobe, biliary dilation in the left lateral section, and a portal vein tumor thrombus. Invasion of the inferior vena cava and the right renal vein were also suspected. Intraoperative findings revealed a large liver tumor that occupied the right lobe and invaded the duodenum and jejunum. The tumor was resected successfully by right trisectionectomy, caudate lobectomy, pancreatoduodenectomy, partial resection of the jejunum, and combined portal vein resection and reconstruction. The inferior vena cava, right kidney, and renal vein could be detached from the tumor. The patient has enjoyed an active life without recurrence for 2 years since the operation.     

Primary osteogenic sarcoma of the breast. Report of a case

Primary osteogenic sarcoma (POS) of the breast is very rare. Only eleven cases have been previously reported in Japan. In this paper, we report an additional case of POS. A 30 year old female was admitted to our hospital with chief complaint of rapidly growing mass of the right breast. She was diagnosed carcinoma of the right breast and underwent a radical mastectomy (Br + Ax + Mj + Mn). Histological findings of the resected tissues revealed POS of the breast. After three months from the operation, local recurrence was demonstrated by an incisional biopsy. One more months later, chest X-P revealed bilateral lung metastases. Irradiation with 60Co for recurrence and chemotherapy using vincristine, methotrexate for distant metastases were not effective. However, cisplatin caused the necrosis of local recurrent tumor. She died nine months after operation. At autopsy, extended metastasis of tumor cells diffusely to the pleura, lungs, liver, adrenal glands, pancreas, peritoneum, fifth lumbar vertebra, skull, dura mater and left pulmonary hilar lymph nodes was observed.     

Utility of expanded anterior column resection versus decompression-alone for local control in the management of carcinomatous vertebral column metastases undergoing adjuvant stereotactic radiotherapy

Background ContextWith improvements in adjuvant radiotherapy and minimally invasive surgical techniques, separation surgery has become the default surgical intervention for spine metastases at many centers. However, it is unclear if there is clinical benefit from anterior column resection in addition to simple epidural debulking prior to stereotactic body radiotherapy (SBRT).PurposeTo examine the effect of anterior column debulking versus epidural disease resection alone in the local control of metastases to the bony spine.Study DesignRetrospective cohort study.Patient SampleNinety-seven patients who underwent open surgery followed by SBRT for spinal metastases at a single comprehensive cancer center.Outcome Measures: Local tumor recurrence following surgery and SBRT.MethodsData were collected regarding radiation dose, cancer histology, extent of anterior column resection, and recurrence. Tumor involvement was categorized using the International Spine Radiosurgery Consortium guidelines. Univariable analyses were conducted to determine predictors of local recurrence and time to local recurrence.Results: Among the 97 included patients, mean age was 60.5±11.4 years and 51% of patients were male. The most common primary tumor types were lung (20.6%), breast (17.5%), kidney (13.4%) and prostate (12.4%). Recurrence was seen in 17 patients (17.5%) and local control rates were: 85.5% (1-year), 81.1% (2-year), and 54.9% (5-year). Overall predictors of local recurrence were tumor pathology (p<.01; renal cell carcinoma and colorectal adenocarcinoma associated with poorest PFS) and undergoing anterior column debulking versus epidural decompression-alone (p=.03). Only tumor pathology predicted time to local recurrence (p<.01), though inspection of Kaplan-Meier functions showed superior long-term local control in patients with radiosensitive tumor pathologies, no previous irradiation of the metastasis, and who underwent anterior column resection versus epidural removal alone. Median time to recurrence was 288 days with 100% of lesions showing anterior column recurrence and recurrence in the epidural space.Conclusions: With the increasing shift towards surgery as a neoadjuvant to radiotherapy for patients with spinal column metastases, the role for surgical debulking has become less clear. In the present study, we find that anterior column debulking as opposed to epidural debulking-alone decreases the odds of local recurrence and improves long-term local control.     

A case of long term survival with skeletal only metastatic breast cancer

IntroductionThe prognosis of patients with metastatic breast cancer is very poor. Because of this, treatment of skeletal metastasis is often palliative with limited goals rather than cure. However, there are those patients, such as presented here, who survive for an extended time.Presentation of caseThis thirty-six year old female presented with lytic lesions to one ulna and rib five years after mastectomy for breast cancer. Despite radiation and chemotherapy, the ulnar lesion expanded and resulted in an elbow dislocation. The rib lesion was resected and the arm amputated above the elbow. She developed local recurrence in both her above elbow amputation stump and chest wall and a more proximal below shoulder amputation was performed with resection of chest wall lesion. Even though she had locally aggressive disease, she has survived for 31 years after diagnosis without any evidence of disease.DiscussionReports of metastatic breast cancer survival indicate the five year survival to be 15%. There have been few reports indicating that those patients with skeletal only or oligometastatic disease have improved prognosis. It is not clear what biological properties of these tumors results in the improved survival.ConclusionThis case highlights the challenges of giving patients the optimal treatment in the light of limited ability to predict prognosis. It also highlights the need to further investigate the phenotypes of breast cancer that can, despite metastatic disease and with modern treatment go on to long survival. In addition this case demonstrates the importance of long term followup.     

Métastases surrénaliennes des carcinomes hépatocellulaires. options thérapeutiques

Aim of the studyThe aim of this study was to evaluate the therapeutic modalities, particularly surgical treatment, for adrenal metastasis of hepatocellular carcinomas.Patients and methodsThis series included 13 patients (mean age: 64 years) with hepatocellular carcinoma on cirrhotic liver (n = 8) or healthy liver (n = 5). The adrenal metastasis was synchronous in four cases, metachronous in nine, unilateral in ten cases, and bilateral in three. Resection of the adrenal metastasis was performed in seven patients, combined with the resection of the hepatic carcinoma in three cases or secondarily performed in four. The metastasis was not resected in six patients because of poor liver function or poor patient conditions; two patients were treated with percutaneous ethanol injection, one with radiation and three received only a symptomatic treatment.ResultsAfter adrenalectomy combined with liver resection, two patients died in the postoperative course in relation with pulmonary embolism (n = 1) or acute pancreatitis (n = 1). The mean survival in the five other patients was 38 months after the adrenalectomy and 58.6 months after the liver resection. After percutaneous ethanol injection, one patient survived 47 months and the other one 7 months only. After radiation, the patient survived 18 months. After symptomatic treatment, the mean survival was only 7.3 months.ConclusionThe present data suggest that adrenal metastasis, either isolated or associated with a well-controlled intrahepatic recurrence, could be treated surgically when the resection is technically feasible. This aggressive management seems the only chance to offer a long-term survival to selected patients.     

Neovascularity and clinical outcome in high-grade extremity soft tissue sarcomas

Background: Increased tumor neovascularity has been shown to correlate with poor prognosis in solid tumors. Methods: Microvessels were identified by factor VIII immunohistochemical staining. Analysis of microvessel counts, tumor characteristics, and resection details was performed on 119 primary, high-grade extremity soft tissue sarcomas (STS) and correlated with clinical outcome. Results: Tumor characteristics and resection details were analyzed and patient outcome was examined with respect to local recurrence, distant metastasis, and disease-specific survival. Factors found to be significant on univariate analysis for all outcome variables were positive microscopic margin and tumor size. A positive microscopic margin was found to be a significant risk factor for local recurrence (P=.03), distant metastasis (P=.006), and disease-specific survival (P=.004). A primary tumor greater than 10 cm in diameter was a poor prognostic factor for distant metastasis (P=.03) and disease-specific survival (P=.006) when compared to tumors smaller than 10 cm. Microvessel count did not correlate with survival nor did it predict distant metastasis or local recurrence. Histologic subtypes of STS that have a prominent vascular pattern as a diagnostic criterion (i.e., angiosarcoma, liposarcoma, hemangiopericytoma) form a subgroup of all STS. Neovascularity in these subtypes showed no relationship to clinical outcome. Conclusions: These data confirm the prognostic importance of microscopic margin and tumor size in high-grade extremity STS. Neovascularity measured by factor VIII staining had no prognostic significance in these mesenchymal tumors, in contradistinction to carcinomas. Alternatively, microvessel counts may not accurately represent the angiogenic capacity of STS. Therefore, patients with STS who are eligible for anti-angiogenesis clinical trials cannot be identified solely by microvessel count.Presented at the 50th Annual Cancer Symposium of The Society of Surgical Oncology, Chicago, Illinois, March 20–23, 1997.     

Hemangiopericytoma/solitary fibrous tumor of pectoralis major muscle mimicking a breast mass

INTRODUCTIONHemangiopericytoma (HPC)/solitary fibrous tumor (SFT) is a very uncommon tumor of uncertain malignant behavior. In 1942, Stout and Murray first characterized these neoplasms as “vascular tumors arising from Zimmerman's pericytes” and till now hemangiopericytomas and solitary fibrous tumors of the soft tissues are regarded as features of the same entity in the soft tissue fascicle.PRESENTATION OF CASEWe present a case of hemangiopericytoma/solitary fibrous tumor of the pectoralis major muscle in a 33-year-old female. She first noticed a painless mass in her right breast. Ultrasound of the breast revealed a large heterogeneously hypoechoic lesion within the pectoralis major muscle. Fine needle aspiration of the tumor did not produce any meaningful result. The lesion was completely removed by surgical resection. Histologically, the tumor had staghorn-like vasculature and immunohistochemistry for CD34 was positive, whereas desmin, smooth-muscle actin, S-100 protein, cytokeratins (AE1/AE3) and epithelial membrane antigen (EMA) were all negative. A diagnosis of hemangiopericytoma/solitary fibrous tumor was rendered.DISCUSSIONTumors comprising the HPC/SFT spectrum represent a small subset of soft tissue sarcomas and are found virtually at any site in the body. Wide surgical resection can achieve favorable long-term survival.CONCLUSIONDue to the rarity and unpredictable biological potential of these tumors, long-term follow-up is mandatory even after radical resection, because recurrence or development of metastasis may be delayed many years.

Abstract：

Objective To explore an optimal treatment and to study the prognosis related factors of breast cancer patients with local recurrence after mastectomy. Methods From 2002. 7 to 2005. 2, 477female patients with loco-regional recurrence of breast cancer treated in Tianjin Cancer Hospital were analyzed retrospectively. Results In 477 cases, recurrence within 1 year after mastectomy accounted for 26. 2% , recurrence within 2 years accounted for 61. 2%. There were 310 cases with metastasis after local recurrence was diagnosed, accounting for 65.0%. 5-year total survival rate after recurrence is 48.4%.Local control rates varied in subgroups with different recurrence site, clinical subtypes, radiotherapy fields,with or without radiotherapy, surgical resection or excisional biopsy ( P<0. 05 ). There was a statistical difference in distant metastasis rate and 5-year survival rate among subgroups which had different clinical stage of primary tumor, disease-free interval, clinical subtypes or treatment methods ( P<0. 05 ). Simplistic treatment option, late clinical stage of primary tumor and triple-negative breast cancer were the independent factors predicting poor prognosis for recurrent breast cancer ( P<0.05 ). Conclusions Multi-site recurrence and triple-negative breast cancer lead to a poor local control. Local expansion of radiotherapy combined with surgery improves the local control rate. Patients with late clinical stage of primary tumor,recurrence within 2 years, triple-negative breast cancer are likely to have distant metastasis when recurrence is diagnosed. Combined treatment program improves survival rate.     

Pulmonary Metastasis From Breast Cancer With an 18-Year Disease-Free Interval: Implication of the Role of Surgery

The appearance of pulmonary metastasis more than 15 years after primary treatment for breast cancer is rare. We herein report the case of a breast cancer patient with solitary pulmonary metastasis, after an 18-year disease-free period, treated with resection. A 66-year-old Japanese woman was found to exhibit an abnormal shadow on a chest X-ray. She had undergone a left mastectomy for breast cancer 18 years previously. The nodule was suspected to be either metastatic or primary lung cancer, and thus thoracoscopic surgery was performed. The histologic diagnosis was metastasis from breast cancer. Pulmonary resection in breast cancer recurrence is an important diagnostic tool that allows for a differential diagnosis with primary lung cancer. The clinical implication of surgery for a solitary pulmonary metastasis from breast cancer is discussed in this report.     

Ischiorectal fossa metastasis from colon cancer: Case report of a rare entity and review of literature

Introduction and importanceColorectal cancer is one of the most common cancers both nationally and internationally. It commonly metastases to local lymph nodes, liver and lungs, with few reported cases of rare sites of metastasis such as adrenal glands, breast and skin.Case presentationWe report a 55-year-old-female admitted as case of large bowel obstruction and unintentional weight loss. Computed tomography scan of chest, abdomen and pelvis (CT CAP) showed sigmoid colon circumferential thickening with three lesions in the right hemi-liver. A laparoscopic diverting ileostomy followed by a colonoscopy showed a sigmoidal mass consistent with adenocarcinoma on histopathology. Hence, she received neoadjuvant chemotherapy followed by hepatectomy for the liver metastasis. Post-operatively CT CAP showed a newly developed right ischiorectal fossa (IRF) nodule along with newly developed porta hepatis lymph node. PET scan showed uptake in these two new lesions. Therefore, the patient underwent resection of the primary tumor, porta hepatis lymph node and right ischiorectal fossa nodule excision. The histopathology of the primary tumor came as moderately differentiated adenocarcinoma with both ischiorectal lesion and the porta hepatis nodule being positive for metastatic disease.Clinical discussion & conclusionIschiorectal fossa tumors are extremely rare with the majority being benign in origin. Nevertheless, the possibility of metastasis is there with no clear explanation regarding the pathway of how the metastatic cells can reach the IRF. Pre-operative diagnosis is important to determine the appropriate approach particularly if the mass is thought to be malignant. Further larger studies are needed to understand the pathway of metastasis to IRF.     

Long-term survival after surgical resection of metachronous lung,brain and thyroid gland metastases from rectal cancer: A case report

Introduction and importanceBrain and thyroid metastasis from rectal cancer are uncommon, and the prognosis is poor. We report a patient with rectal cancer who developed metachronous lung, brain and thyroid metastases. Each metastatic lesion was curatively resected resulting in prolonged survival.Case presentationA 60-year-old male underwent rectal cancer resection, and the pathological diagnosis was tubular adenocarcinoma, pT2,pN1a,M0, pStageⅢa. Ten years after rectal resection, a solitary tumor in the left lung was detected. The tumor was resected thoracoscopically and the pathological diagnosis was metastatic tumor. Three years after the pulmonary resection, a solitary brain tumor was detected. The tumor was removed surgically, and the pathology was metastatic tumor. Two years after brain resection, a thyroid mass was detected. A partial thyroidectomy was performed and the pathology with immunohistochemical staining confirmed the thyroid lesion as a metastasis from the previous rectal cancer. Four years after thyroid resection (19 years after the initial rectal resection), he died from multiple lung and bone metastases.Clinical discussionColorectal metastases to the brain and thyroid gland are uncommon and are usually found with other distant metastases. Overall survival has been reported to be extremely poor. In this patient, lung, brain, and thyroid metastases were solitary and metachronous, and each lesion was curatively resected. Surgical treatment might contribute to prolonged survival.ConclusionThe treatment strategy of each patient should be individualized and depends on the timing of metastasis development. Selected patients with complete resection of metachronous metastases may have prolonged survival.     

Is conservative surgery a good option for patients with “triple negative” breast cancer?

BackgroundTriple negative breast cancers (negative estrogen receptor, progestagen receptor and no overexpression of HER2) seems to be more aggressive than other breast carcinoma subtypes. Therefore, it is necessary to analyze if a more aggressive surgical treatment should be offered to this subgroup of patients.Patients and methodsThe Castellon Cancer Registry Database (C.Valenciana, Spain) was used to identify eligible breast cancer patients. Female patients who were diagnosed and/or treated from January 2000 to December 2008 with primary, invasive, unilateral breast cancer at our hospital were included. A total of 410 patients make up the study population. Kaplan–Meier curves and log-rank tests were used to estimate 5-year local recurrence functions and to compare them across strata. Cox proportional hazards models were used to calculate hazard ratios and 95% confidence intervals to fit the effect of conservative surgery and other independent variables on local recurrence.ResultsMedian follow-up time was 60 months (1–127 months). A total of 21 patients (5%) presented a local recurrence during follow-up. There was a 9% difference in terms of local recurrence between conservative and non-conservative techniques for triple negative patients, whereas such difference was only 1% for no triple negative patients. On univariate analysis for local recurrence, only tumor size and lymph node metastasis were statistically associated with local recurrence. All other variables (type of surgery, triple negative status, molecular classification, tumor grade, age, adjuvant treatments, and total number of analyzed lymph nodes) were not statistically significant. On multivariate analysis, independent prognostic factors were breast conservative surgery (HR 4.62 95%CI 1.12–16.82), number of positive lymph nodes (HR 1.07 95%CI 1.01–1.17) and millimetre tumor size (HR 1.02 95%CI 1.01–1.06). In contrast, triple negative status trended to be a risk factor but without statistical significance (HR 1.59 95%CI 0.42–8.04).ConclusionsIt was not possible to find statistically significant differences between conservative and non-conservative surgery for triple negative breast cancer. However, a trend was observed for higher recurrence rates after breast conservative surgery for this group of patients. Prospective clinical trials are needed to confirm this observation.     

Factors associated with local breast cancer recurrence after lumpectomy alone

Background: The purpose was to determine the rate of local breast relapse in patients with breast cancer uniformly treated with partial mastectomy but without postoperative radiotherapy and without systemic adjuvant therapy. We also systematically examined the factors associated with local recurrence to determine whether a low-risk subgroup existed. Methods: A retrospective review of a prospectively followed (median, 8 years) cohort of 293 patients was performed. The end-point was ipsilateral local breast cancer recurrence. The patient's age, tumor size, nodal status, estrogen and progesterone receptor status, histology, and tumor and nuclear grade were studied, as were the presence and amount of carcinoma in situ and the presence of tumor emboli using univariate Kaplan-Meier and Cox step-wise multivariate analyses. Results: The overall local relapse rate was 26% (77 recurrences). Univariate factors significantly associated with decreased local relapse included older age, negative nodes, small tumor size, positive estrogen receptor status, and absence of tumor emboli. Significant multivariate variables were age, nodal status, estrogen receptor status, absence of comedo carcinoma in situ, and tumor emboli. A low-risk subgroup of 66 patients was defined with a 6% 10-year local recurrence rate. Conclusion: Important patient and tumor variables associated with local breast cancer relapse after breast-conserving surgery can define a low-risk subgroup.     

Chest wall resection and reconstruction for recurrent breast cancer – A multidisciplinary approach

BackgroundDespite therapeutic advances in the management of breast cancer, a significant number of patients present with locoregional recurrence. Treatment with hormonal, chemo or radiotherapy remains standard in such cases. However, in selected patients of recurrent breast cancer involving chest wall, multidisciplinary surgical approach could be considered.MethodsBetween 2010 and 2018, 21 patients with recurrent breast cancer, involving chest wall, were treated at a tertiary care center with resection and reconstruction. The mean age of the patients was 55 years (22–77 years).ResultsThe median interval from first breast resection to chest wall resection (CWR) for recurrent disease was 6 years (1–24 years). Eighteen patients underwent bony resection and 3 patients required extensive soft tissue resection. Complete resection was achieved in 90% of patients. All patients had chest wall reconstruction. There was no in-hospital mortality. During follow-up, 8 patients died, of which 7 were due to distant metastases. The 1 year and 3-year overall survival were 90% (95% CI 66–97) and 61% (95% CI 31–81) respectively. The disease-free survival at 1 and 3 years was the same at 70% (95% CI 45–86). At a mean follow up of 23 months, the average survival in patients operated for local recurrence is 51.7 months (95% CI 37.7–65.7) and 24.5 months (95% CI 7.3–41.7) for patients with distant metastatic recurrence.ConclusionA multidisciplinary oncoplastic approach for recurrent breast cancer, which includes chest wall resection and reconstruction is a useful adjunct in selected group of patients. This improves local disease control, symptoms and possibly disease-free survival.
