Impact of Routine Cavity Shave Margins on Breast Cancer Re-excision Rates

Purpose

Breast-conserving therapy (BCT) is an accepted method of treating early breast cancer. We hypothesized that routine excision of additional cavity shave margins (CSM) at time of initial partial mastectomy reduces the need for additional surgery.

Methods

A single-institution retrospective review was performed of women, 18 years or older, with a new diagnosis of breast cancer who underwent partial mastectomy between 1 January 2004 and 1 October 2009. Five hundred thirty-three charts were reviewed. Of those, 69 patients underwent CSM at time of initial operation. These 69 patients were matched with patients who had undergone partial mastectomy without CSM by tumor size, presence of extensive intraductal component, and primary histology.

Results

The two groups were well matched for age, nuclear grade, associated lymphovascular invasion (LVI), receptor status, and multifocality. We found that 31.9% (44/138) required return to the operating room (OR) for re-excision of margins. Rate of return to the OR was 21.7% (15/69) in the CSM group and 42.0% (29/69) in the matched group (p = 0.011). Multivariate analysis found factors significantly associated with need for additional operation included lack of CSM (odds ratio 9.2, 95% CI 2.8–30.5, p = 0.0003), larger extent of intraductal component (odds ratio 7.0, 95% CI 1.8–27.0, p = 0.005), and lack of directed re-excision (odds ratio 6.4, 95% CI 1.7–25.1, p = 0.007).

Conclusions

CSM at time of initial partial mastectomy decreases rate of re-excision by as much as ninefold. CSM should be considered at time of initial operation to reduce the need for subsequent reoperation.     

Radiocolloid in Combination with Methylene Dye Localization, Rather Than Wire Localization, is a Preferred Procedure for Excisional Biopsy of Nonpalpable Breast Lesions

Background

Wire localization (WL) is traditionally performed before excisional biopsy for patients with nonpalpable breast lesions, but it has several disadvantages. Our current study examines whether the method of radiocolloid combined with methylene dye localization (RCML) has an advantage over WL.

Materials and Methods

From August 2006 to May 2009, 157 patients with nonpalpable breast lesions classified as BI-RADS category 5 were enrolled in our study. Of the 157 patients, 78 were assigned to WL and 79 to RCML. The status of surgical margins, weight of specimens, length of incisions, and duration of operation were compared between these two groups.

Results

All patients were diagnosed after first excisional biopsy. The patients with malignancy accounted for 55.1% in WL group, and 53.2% in RCML group. For malignant lesions, fewer patients undergoing RCML had close or involved surgical margins than did those who had WL (19.0% vs. 39.5%, P = .038). The mean weight of specimen was 45.2 g in WL group and 39.0 g in RCML group (P < .001). The mean length of incision was 44.8 mm in WL group and 36.3 mm in RCML group (P < .001). The mean time of operation was 16.3 min for WL and 14.7 min for RCML (P = .001).

Conclusions

RCML provides precise identification of the site of the nonpalpable lesion and a visible marker to the lesion for surgeons and allows rapid, easy, and accurate excision of nonpalpable breast lesions. Therefore, RCML is a promising alternative to WL.     

Re-Excision Rates of Invasive Ductal Carcinoma with Lobular Features Compared with Invasive Ductal Carcinomas and Invasive Lobular Carcinomas of the Breast

Background

Invasive ductal carcinoma (IDC) with lobular features (IDC-L) is not recognized as a subtype of breast cancer. We previously showed that IDC-L may be a variant of IDC with clinicopathological characteristics more similar to invasive lobular carcinoma (ILC). We sought to determine the re-excision rates of IDC-L compared with ILC and IDC, and the feasibility of diagnosing IDC-L on core biopsies.

Methods

Surgical procedure, multiple tumor foci, tumor size, and residual invasive carcinoma on re-excision were recorded for IDC-L (n = 178), IDC (n = 636), and ILC (n = 251). Re-excision rates were calculated by excluding mastectomy as first procedure cases and including only re-excisions for invasive carcinoma. Slides of correlating core biopsies for IDC-L cases initially diagnosed as IDC were re-reviewed.

Results

For T2 tumors (2.1–5.0 cm), re-excision rates for IDC-L (76 %) and ILC (88 %) were higher than that for IDC (42 %) (p = 0.003). Multiple tumor foci were more common in IDC-L (31 %) and ILC (26 %) than IDC (7 %) (p < 0.0001), which was a significant factor in higher re-excision rates when compared with a single tumor focus (p < 0.001). Ninety-two of 149 patients (62 %) with IDC-L were diagnosed on core biopsies. Of the 44 patients initially diagnosed as IDC, 30 were re-reviewed, of which 24 (80 %) were re-classified as IDC-L.

Conclusions

Similar to ILC, re-excision rates for IDC-L are higher than IDC for larger tumors. Patients may need to be counseled about the higher likelihood of additional procedures to achieve negative margins. This underscores the importance of distinguishing IDC-L from IDC on core biopsies.     

Radioactive Seed Localization Compared to Wire Localization in Breast-Conserving Surgery: Initial 6-Month Experience

Background

Wire localization (WL) of nonpalpable breast cancers on the day of surgery is uncomfortable for patients and impacts operating room efficiency. Radioactive seed localization (RSL) before the day of surgery avoids these disadvantages. In this study we compare outcomes of our initial 6-month experience with RSL to those with WL in the preceding 6 months.

Methods

Lumpectomies for invasive or intraductal cancers localized with a single ¹²⁵iodine seed (January–June 2012) were compared with those using 1 wire (July–December 2011). Surgeons and radiologists did not change. Positive and close margins were defined as tumor on ink and tumor ≤1 mm from ink, respectively. Demographic and clinical characteristics and outcomes were compared between RSL and WL patients.

Results

There were 431 RSL and 256 WL lumpectomies performed. Clinicopathologic characteristics did not differ between groups. Most seeds (90 %) were placed before the day of surgery. Positive margins were present in 7.7 % of RSL versus 5.5 % of WL patients, and 16.9 % of RSL versus 19.9 % of WL had close margins (p = 0.38). The median operative time was longer for lumpectomy and sentinel lymph node biopsy (SLNB) in the RSL group (55 vs. 48 min, p < 0.0001). There was no significant difference in the volume of tissue excised between groups.

Conclusions

In the first 6 months of RSL, operative scheduling was simplified, while rates of positive and close margins were similar to those seen after many years of experience with WL. Operative time was slightly longer for RSL lumpectomy and SLNB; we anticipate this will decrease with experience.     

Margin Width Should Not Still Enforce a Systematic Surgical Re-excision in the Conservative Treatment of Early Breast Infiltrative Ductal Carcinoma

Background

In cases where breast conservative surgery was performed for infiltrative ductal carcinoma (IDC), margin status is an independent prognostic factor for local ipsilateral relapse (LIR). There is no validated definition of a clear margin. We investigated factors associated with residual disease on re-excision specimen and the impact of margin status on the risk of LIR.

Methods

From January 1992 to December 2002, 454 patients were retrospectively included. Patients had undergone conservative surgery and radiotherapy for IDC. Two groups were defined: group 1, involved or close margin (<3 mm) and a re-excision; and group 2, involved or close margin without re-excision. The risk factors for residual disease in the re-excision specimen were analyzed in group 1, and the rate of 5-year LIR was analyzed in both groups.

Results

Among patients who experienced a surgical re-excision for involved or close margin, 21 % (55 of 206) had residual tumor. The multivariate analysis showed that only a margin involved with intraductal carcinoma remained predictive for residual disease. According to the multivariate analysis, only hormone therapy (p < 10^?6), diffuse involved margins (p = 0.003), and margins involved with intraductal component (p < 10^?6) were predictive of LIR. Re-excision for a margin involved with intraductal carcinoma significantly improved local relapse-free survival (p < 0.001).

Conclusions

In cases of IDC, re-excision for a close margin or a focally involved margin had no impact on local relapse-free survival. The decision to perform a surgical re-excision for an involved margin should not be systematic but should take multiple risk factors into consideration, such as patient age or margin diffuse involvement.     

Trends in Incidence and Management of Lobular Carcinoma In Situ: A Population-Based Analysis

Purpose

Lobular carcinoma in situ (LCIS) is a marker of increased risk of breast cancer. Current guidelines do not recommend mastectomy as a strategy for risk reduction for most patients with LCIS. We conducted a population-based study to evaluate national trends in incidence and management of LCIS.

Methods

Using the Surveillance, Epidemiology, and End Results database, we conducted a retrospective cohort analysis of women diagnosed with microscopically confirmed LCIS from 2000 through 2009. We excluded patients with invasive breast cancer or ductal carcinoma in situ. We evaluated variation in treatment, including biopsy alone, excision, excision with radiation therapy, and mastectomy. We utilized logistic regression to identify time trends, demographics, and patient factors associated with mastectomy.

Results

We identified 14,048 patients diagnosed with LCIS from 2000 to 2009. The rate of LCIS incidence increased from 2.0 per 100,000 in 2000 to 2.75 per 100,000 in 2009 (38 % increase). Of these patients, 10 % underwent biopsy only, 73 % underwent excision alone, 1 % underwent excision with radiation, and 16 % underwent mastectomy. Mastectomy rates were significantly higher among white and younger women. The proportion of women with LCIS to receive mastectomy increased by 50 % from 2000 to 2009 (p < 0.01). Mastectomy rates varied significantly based on geographic region ranging from 12 to 24 %.

Conclusions

This is the first population-based analysis evaluating patterns and trends in surgical management of LCIS. Despite current recommendations, risk-reduction surgery is increasingly performed in the United States for women with LCIS.     

Localizing High-Risk Lesions for Excisional Breast Biopsy: A Comparison Between Radioactive Seed Localization and Wire Localization

Background

Improved resolution and utilization of screening breast imaging has increased identification of nonpalpable high-risk lesions (HRL) and subsequent excisional breast biopsies (EBBs). Wire localization (WL), used most commonly for EBBs, may have shortcomings, including wire displacement, patient discomfort, limitations with incision planning and scheduling logistics. Radioactive seed localization (RSL) may overcome these drawbacks. The purpose of this study was to compare WL and RSL for EBBs for HRLs.

Methods

All single-site EBBs for HRL performed by four breast surgeons were retrospectively reviewed over two consecutive 1-year periods. Patients with cancer on percutaneous core biopsy (CB) were excluded. Clinicopathologic information, operative time, targeted lesion retrieval rate, and upstage rate were collected.

Results

A total of 324 EBBs for HRL were performed: 196 using WL and 128 using RSL. CB pathology was atypical hyperplasia in 56 % of WLs and 62 % of RSLs. The remaining pathologies were radial scar, papilloma, atypical papilloma or lobular carcinoma in situ. Mean age was 54 years. OR time was 27 ± 8 min for WL and 27 ± 7 min for RSL (p = 0.9). Upstage rate was 6 and 5 % for WLs and RSLs, respectively (p = 0.5). Targeted lesions were retrieved in 98 % of WL and 99 % of RSL (p = 0.5). SV was 37.2 ± 32.8 cm³ and 25.7 ± 22.3 cm³ for WL and RSL, respectively (p = 0.001).

Conclusions

RSL is comparable to WL for EBB of HRLs with similar OR times and upstage rates. SV is significantly decreased with RSL and may translate into improved cosmetic outcomes without sacrificing the diagnostic accuracy of the EBB.     

The DNA index is a strong predictive marker in intrahepatic cholangiocarcinoma: the results of a five-year prospective study

Purpose

Predictive markers for risk stratification among patients with intrahepatic cholangiocarcinoma (IHC) are still lacking. Therefore, recent studies have focused on identifying the biological aspects of tumors that can provide more information about the tumor aggressiveness. The aim of this study was to prospectively evaluate the prognostic potential of the DNA index in patients undergoing liver resection for IHC.

Methods

In a prospective long-term follow-up study, the DNA index of 65 IHC patients undergoing liver resection was assessed by DNA image cytometry, and this parameter, as well as standard histopathological parameters, correlated with the patient survival.

Results

The mean DNA index was 1.69 ± 0.66 (range, 0.9–4.3). The univariate survival analysis showed that the DNA index (p = 0.024) and tumor stage (p = 0.017) were associated with patient survival, whereas all other standard histopathological factors had no predictive value. The multivariate analysis identified the DNA index (p = 0.050) and tumor stage (p = 0.028) as independent prognostic parameters.

Conclusions

The DNA index is an independent predictive marker for IHC after liver resection. It is superior to most standard histopathological parameters and can be assessed pre- and postoperatively. Therefore, the DNA index might represent a promising tool in the decision-making process for patients with IHC.     

Paravertebral Blocks in Patients Undergoing Mastectomy with or without Immediate Reconstruction Provides Improved Pain Control and Decreased Postoperative Nausea and Vomiting

Background

Mastectomy is associated with postoperative nausea and pain. We evaluated whether paravertebral block (PVB) use altered opioid use, antiemetic use, and length of stay in patients undergoing mastectomy.

Methods

We performed a retrospective cohort analysis of all patients who underwent mastectomy with or without PVB from 2008 to 2010. Patient demographics, operative procedure, intraoperative medications, postoperative opioid and antiemetic use, and length of stay were reviewed. Statistical analysis included univariable and multivariable analysis.

Results

A total of 605 patients were identified, of whom 526 patients were evaluable. A total of 294 patients underwent mastectomy without PVB (132 bilateral), and 232 patients underwent mastectomy with PVB (148 bilateral). Immediate reconstruction was performed in 203 (39 %) patients. Need for any postoperative antiemetic was less frequent in the PVB group (39 vs. 57 %, p < 0.0001). Day of surgery opioid use was lower in the PVB group than the non-PVB group (mean ± SD 40.1 ± 15.2 vs. 47.6 ± 17.7 morphine equivalents, p < 0.0001). Decreased opioid use was seen in unilateral mastectomy without reconstruction and bilateral mastectomy with and without immediate reconstruction. The proportion of patients discharged within 36 h of surgery was significantly higher in the PVB group (55 vs. 42 %, p = 0.0031). On multivariable analysis controlling for year of surgery, patient age and surgeon, PVB use affected antiemetic use and opioid use but not hospital length of stay.

Conclusions

PVB results in decreased opioid use and decreased need for postoperative antiemetic medication in patients undergoing mastectomy. The greatest benefit is seen in patients undergoing bilateral mastectomy with immediate breast reconstruction.     

Hexaminolevulinate-guided transurethral resection of non-muscle-invasive bladder cancer does not reduce the recurrence rates after a 2-year follow-up: a prospective randomized trial

Purpose

To assess the impact of hexaminolevulinate (HAL) on the long-term recurrence rate of NMIBC.

Methods

A total of 130 patients with bladder tumour were randomized into two groups. The patients in one group had a HAL instillation before surgery, and they first had a white-light and after that a blue-light cystoscopy (BL group) and resection. The second group had only white-light cystoscopy (WL group) and resection. They have been followed up with cystoscopy every 3 months for a period of up to 40 months.

Results

The recurrence-free period was not significantly different between the two groups (BL and WL groups) (long-rank test p = 0.202). The use of HAL helped detect four flat lesions and 28 papillary lesions with cancer that would have been missed under WL only, on 16 out of the 54 patients (29.6 % CI 95 % 11.1–33.3). The use of HAL changed the proposed postoperative treatment and follow-up for one out of the five patients.

Conclusions

Although the use of HAL cystoscopy identified at least one cancer lesion more than WL cystoscopy on one out of the three patients, the recurrence-free period was not significantly different.     

Increasing National Mastectomy Rates for the Treatment of Early Stage Breast Cancer

Background

To study national trends in the mastectomy rate for treatment of early stage breast cancer.

Methods

We analyzed data from the Surveillance, Epidemiology, and End Results database, including 256,081 women diagnosed with T1–2 N0–3 M0 breast cancer from 2000 to 2008. We evaluated therapeutic mastectomy rates by the year of diagnosis and performed a multivariable logistic regression analyses to determine predictors of mastectomy as the treatment choice.

Results

The proportion of women treated with mastectomy decreased from 40.1 to 35.6 % between 2000 and 2005. Subsequently, the mastectomy rate increased to 38.4 % in 2008 (p < 0.0001). Simple logistic regression models demonstrated that mastectomy rates between 2005 and 2008 were moderated by age (p < 0.0001), marital status (p = 0.0230), and geographic location (p < 0.0001). Multivariate logistic regression analysis found that age, race, marital status, geographic location, involvement of multiple regions of the breast, lobular histology, increasing T stage, lymph node positivity, increasing grade, and negative hormone receptor status were independent predictors of mastectomy. Additionally, multivariate analysis confirmed that women diagnosed in 2008 were more likely to undergo mastectomy than women diagnosed in 2005 (odds ratio 1.17, 95 % confidence interval 1.13 to 1.21, p < 0.0001).

Conclusions

There is evidence of a reversal in the previously declining national mastectomy rates, with the mastectomy rate reaching a nadir in 2005 and subsequently rising. Further follow-up to confirm this trend and investigation to determine the underlying cause of this trend and its effect on outcomes may be warranted.     

Comparison of platelet count in tuberculosis spine to other spine pathology

Purpose

Haematological markers currently used to investigate TB spine vary from WCC, Anaemia, ESR and CRP. Platelet count in TB spine as a marker has been inadequately investigated.

Method

In this retrospective review, Platelet count in TB spondylitis on admission was compared to patients undergoing other elective spinal surgery (control) preoperatively. Comparisons of the platelets with ESR and the effect of HIV on platelet count in TB spine were also evaluated.

Results

160 TB spine patients showed statistically significant higher platelet count when compared to 210 patients in the control group (p < 0.001). 52.5 % patients had a raised platelet count in the TB spondylitis group. Raised Platelet count had a sensitivity and specificity of 52.5 % and 86.2 %, respectively in TB spondylitis. ESR and platelet count had a Pearson correlation r = 0.31 (p < 0.001). HIV however did not statistically show any difference in the platelet count (p = 0.12).

Conclusion

A raised platelet count in spinal pathology may be used as an inflammatory marker of TB spondylitis.     

Incidence and Consequence of Close Margins in Patients with Ductal Carcinoma-In Situ Treated with Mastectomy: Is Further Therapy Warranted?

Background

The impact of close margins in patients with ductal carcinoma-in situ (DCIS) treated with mastectomy is unclear; however, this finding may lead to a recommendation for postmastectomy radiotherapy (PMRT). We sought to determine the incidence and consequences of close margins in patients with DCIS treated with mastectomy.

Methods

The records of 810 patients with DCIS treated with mastectomy from 1996 through 2009 were reviewed. Clinical and pathologic factors were analyzed with respect to final margin status. Median follow-up was 6.3 years.

Results

Overall, 94 patients (11.7 %) had close margins (positive, n = 5; negative but ≤1 mm, n = 54; 1.1–2.9 mm, n = 35). Independent risk factors for close margins included multicentricity, pathologic lesion size ≥1.5 cm, and necrosis, but not age, use of skin-sparing mastectomy, or immediate reconstruction (p > 0.05). Seven patients received PMRT, and none had a locoregional recurrence (LRR). Among the remaining 803 patients, the 10-year LRR rate was 1 % (5.0 % for margins ≤1 mm, 3.6 % for margins 1.1–2.9 mm, and 0.7 % for margins ≥3 mm [p < 0.001]). The 10-year rate of contralateral breast cancer was 6.4 %. On multivariate analysis, close margins was the only independent predictor of LRR (p = 0.005).

Conclusions

Close margins occur in a minority of patients undergoing mastectomy for DCIS and is the only independent risk factor for LRR. As the LRR rate in patients with close margins is low and less than the rate of contralateral breast cancer, PMRT is not warranted except for patients with multiple close/positive margins that cannot be surgically excised.     

Development of breast cancer-related lymphedema: is it dependent on the patient, the tumor or the treating physicians?

Introduction

Breast cancer-related lymphedema (LE) is relatively common. The aim of this study was to identify the risk factors involved in the development of this complication.

Methodology

This was a cross-sectional study of breast cancer patients treated at our Center between 2004 and 2009. A total of 515 patients were included. Lymphedema was defined as a mid-arm or forearm circumference difference between both limbs of 2 cm or more.

Results

The incidence of LE in this population was 21.4 %. Patients with a BMI of 25 or higher had a significantly higher risk of LE (p = 0.002). The presence of lymphovascular invasion (LVI) (p = 0.05) and the number of positive lymph nodes (LN) (p = 0.001) were both associated with LE. Patients who underwent axillary dissection (AD) had a significantly higher incidence of LE than patients who had a sentinel LN biopsy (25 vs. 4.5 %). Adjuvant radiotherapy was also a significant risk factor in patients who had a mastectomy (p = 0.003).

Conclusion

There are multiple risk factors for LE. Most of those factors can be influenced by early tumor detection. Early tumors are smaller with no LVI or axillary LN metastasis. They do not usually require AD or axillary radiotherapy, which are the strongest factors associated with the development of LE.     

Significance of Serum Tumor Marker Levels in Peritoneal Carcinomatosis of Appendiceal Origin

Background

The significance of tumor markers in patients with appendiceal carcinomatosis is poorly defined. We determined preoperative and postoperative tumor marker levels in patients undergoing cytoreductive surgery (CRS) and heated intraperitoneal chemoperfusion (HIPEC) and examined their association with clinicopathologic features and survival.

Methods

A total of 176 patients undergoing attempted CRS/HIPEC for appendiceal carcinomatosis had at least 1 tumor marker measured. Marker levels were correlated with tumor characteristics and oncologic outcomes. Kaplan–Meier curves and multivariate Cox regression models were used to identify prognostic factors affecting progression and survival.

Results

At least 1 marker was elevated prior to CRS/HIPEC in 70 % of patients (CEA, 54.1 %; CA19-9, 47.7 %; CA-125, 47.2 %). Among patients with elevated preoperative marker levels, normalization occurred postoperatively in 79.4 % for CEA, 92.3 % for CA19-9, and 60 % for CA-125. Absolute preoperative tumor marker levels correlated with peritoneal carcinomatosis index (PCI) (p < .0002), and the number of elevated markers was associated with PCI and progression-free survival (PFS). Elevated postoperative CEA level was associated with decreased PFS (median, 13 vs 36 months, p = .0008). On multivariate Cox regression analysis, elevated preoperative CA19-9 was associated with shorter PFS (hazard ratio [HR] 2.9, 95 % confidence interval [95 % CI] 1.5–5.3, p = .0008), whereas elevated CA-125 was associated with shorter overall survival (HR 2.6, 95 % CI 1.3–5.4, p = .01).

Conclusions

Most patients with appendiceal carcinomatosis will have at least 1 elevated tumor marker and will normalize following CRS/HIPEC, allowing for ongoing surveillance. CA19-9 is a promising biomarker for early progression following CRS/HIPEC, whereas CA-125 is associated with shorter survival.     

Is Axillary Lymph Node Dissection Necessary After Sentinel Lymph Node Biopsy in Patients with Mastectomy and Pathological N1 Breast Cancer?

Background

The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial reported that axillary lymph node dissection (ALND) did not change the recurrence and overall survival (OS) rates in patients with lumpectomy and one to two positive nodes detected by sentinel lymph node biopsy (SLNB). The aim of this study was to determine whether patients with mastectomy and pathological N1 disease found by SLNB could forego ALND.

Materials and Methods

This is a retrospective study of 214 patients diagnosed with primary invasive breast cancer who were treated by mastectomy and lymph node staging surgery (SLNB or ALND) at the Revlon/UCLA Breast Center between January 2002 and December 2010. Patients with pathological N1 disease were separated by their first nodal surgery into SLNB (subgroups: observation, radiation, and additional ALND with or without radiation) and ALND groups (subgroups: ALND with or without radiation).

Results

After a median follow-up of 43.6 months, the OS and systemic relapse-free survival (RFS) rate of the radiation group and additional ALND group were significantly better than the observation group (p = 0.031 and 0.046, respectively). Human epidermal growth factor receptor 2 (HER2) expression was found to predict OS and patients’ age, histological grade and HER2 expression predicted systemic recurrence. Compared with the SLNB group, pain (p = 0.021) and lymphedema (p = 0.043) occurred more frequently in the ALND group.

Conclusion

Radiation was as effective as ALND in patients with mastectomy and N1 disease for OS and RFS rates, yet radiation after SLNB had fewer side effects than ALND. SLNB followed by radiation could replace ALND in patients with mastectomy and pathological N1 breast cancer identified by SLNB.     

Impact of residual disease after “unplanned excision” of primary localized adult soft tissue sarcoma of the extremities: evaluation of 452 cases at a single Institution

Background

Soft tissue sarcomas are often inappropriately excised; it is, however, still a matter of debate whether the presence of residual disease in the re-excision specimen can affect patients’ prognosis. The aim of this study is to investigate the impact of re-excision after unplanned surgery of primary soft tissue sarcomas (STS) of the extremities.

Patients and methods

We retrospectively evaluated 452 adults with grade 2–3, localized STS (349 primary and 103 unplanned excisions).

Results

In the re-excision group, a full 43% of the patients had residual tumor. The re-excision group achieved a significantly better outcome in terms of sarcoma-specific survival (SS) (p = 0.002), local recurrence (LR) (p = 0.004) and distant metastasis (DM) (p = 0.028). Residual tumor was associated with a higher risk of DM (p = 0.005).

Conclusion

We confirm that unplanned surgery does not compromise patients’ prognosis; scar re-excision guarantees at least the same SS, LR and DM rates compared to STS primarily treated in a referral center. Routine use of radiation therapy after re-excision could improve local control. Distant metastases seem to be negatively affected by the presence of residual tumor, and therefore, the use of CT in deep and large STS is suggested. The main goal is to avoid unplanned surgery by referring suspected lumps (especially deep, large, increasing in size) to a specialist center.

     

Factors Influencing Surgical and Adjuvant Therapy in Stage I Breast Cancer: A SEER 18 Database Analysis

Background

Randomized trials have shown no survival difference for patients with stage I breast cancer treated with mastectomy versus breast-conserving surgery (BCS) with radiotherapy (RT). RT is recommended after BCS in order to decrease local recurrence and mortality. We sought to evaluate the treatment trends in patients with stage I breast cancer.

Methods

We used the Surveillance, Epidemiology, and End Results (SEER) database to identify 194,860 women with stage I breast cancer diagnosed from 1988 to 2007. We evaluated factors that were associated surgical treatment and the utilization of RT after BCS.

Results

There was a progressive decline in the proportion of patients with stage I breast cancer who were treated with mastectomy from 1998 to 2007. Significant predictors for being treated with mastectomy included single/divorced women (p = 0.007), white race (p < 0.001), estrogen receptor negativity (p < 0.001), earlier year of diagnosis (p < 0.001), smaller tumor size (p < 0.001), and region (p < 0.001). Twenty percent of the BCS cohort did not receive RT, and this proportion did not change over time. Significant predictors for not receiving RT included small tumor size (p < 0.001), African American race (p < 0.001), increasing age (p < 0.001), single/divorced women (p < 0.001), estrogen receptor negativity (p < 0.001), and region (p < 0.001). The survival for patients treated with BCS and RT was significantly higher than for those who did not receive RT (p < 0.001).

Conclusions

The use of BCS for the treatment of stage I breast cancer increased over time. A constant proportion of patients did not receive RT after BCS. Omission of RT in BCS is associated with an increase in mortality.     

Effect of Delayed Autologous Breast Reconstruction on Breast Cancer Recurrence and Survival

Background

The goal of the present study was to evaluate the impact of delayed autologous breast reconstruction on disease relapse in breast cancer patients treated with mastectomy.

Material and methods

The study was based on 503 consecutive patients younger than 70 years of age who underwent mastectomy between January 2000 and December 2003. Overall, 391 (78 %) received mastectomy alone and 112 (22 %) underwent a delayed breast reconstruction. The median time from mastectomy to delayed breast reconstruction was 34 months. The median duration of follow-up was 102 months.

Results

There were no locoregional recurrences (LRR) in patients who underwent delayed reconstruction (0.0 %); 21 LRR developed in patients treated with mastectomy only (5.4 %), P = 0.011. Distant metastases occurred less frequently in the reconstruction group (12.5 %) than in the patients who underwent mastectomy alone (21.5 %); P = 0.0343. The 8-year breast cancer specific survival in the reconstruction group was 98.2 and 85.7 % for the mastectomy only group, P = 0.000.

Conclusions

Delayed autologous breast reconstruction does not appear to adversely influence disease progression when compared to patients treated with mastectomy only.
