   Abstract 


Context: Lymphangiogenesis correlates with poor prognosis in Invasive Ductal Carcinoma (IDC) breast. D2-40 antibody, a specific marker for lymphatic endothelium, differentiates lymphatic from vascular endothelium. Therefore, the aims of this study were to estimate lymphangiogenesis using D2-40 antibody and correlate with lymphatic invasion (LI) and axillary lymph node (LN) status and compare lymphatic mean vessel density (LMVD) with Tumor (T) and Node (N) stages and grade of tumor. Methods and Material: The study was conducted on fifty consecutive cases of IDC breast who underwent modified radical mastectomy (MRM) from Jan 2009 to March 2011. Hematoxylin-eosin sections and Immunohistochemistry (IHC) slides were studied along with their LN status. LMVD was counted after D2-40 immunostaining (100x magnification) in three hot spots in peritumoral areas and averaged. LI as opposed to vascular invasion (BVI), and LN status for all cases were assessed. Statistical Analysis: Statistical analysis was done using SPSS software (version 14.0 for Windows). Pearson's correlations, χ2 tests and Mann-Whitney U test were used. Results: Lymphangiogenesis varied from 0 to 58 with mean LMVD of 11. Of 50 cases, five showed no lymphatic vessels in peritumoral areas; of these five, three had positive LNs. 21/50 cases had LI. No statistical significant association was seen between lymphangiogenesis and LI. 34/50 cases had positive LNs. Mean LMVD was higher in patients with N2/N3 stage as compared to N0/N1 stage and was statistically significant (P = 0.013). Conclusions: D2-40 is specific marker for lymphatic endothelium. LI and lymphangiogenesis, as opposed to BVI, are better prognostic indicators in IDC breast.

   Introduction Top


Metastasis is the leading cause of mortality in patients of breast cancer (BC)[1] and other solid tumors.[2] Frequently, the initial sites of metastasis are the regional lymph nodes (LNs).[3],[4] Migration of tumor cells into the LNs is greatly facilitated by lymphangiogenesis, a process that generates new lymphatic vessels from preexisting lymphatics [5],[6] or from lymphatic endothelial progenitors. This process is dynamic during embryogenesis but is relatively rare in adulthood. Lymphangiogenesis after staining with specific markers is found in greater numbers in regions with BCs as compared to normal breast parenchyma.[7],[8] An increased lymphangiogenesis is found to be associated with increased LN positivity.[9],[10]

Lymphatic metastasis may not exclusively depend on the generation of new vessels, although undoubtedly, increase in lymph mean vessel density (LMVD) significantly increases the potential for a tumor cell to invade lymphatic vessel surface. This may account for strong statistical associations between lymphovascular invasion (LVI) encompassing both preexisting and new vessels and LN metastasis.[11],[12] It is possible, however, that in some cases, breast tumors fail to induce lymphangiogenesis so that lymphatic metastasis occurs only through the preexisting vessels.[12] New lymphatic vessels may provide an additional track for tumor cell transit, thus bolstering the prometastatic activity of the preexisting lymphatic vessels situated at the tumor border.[11] This fact led to the concept of quantification of tumor lymphangiogenesis (LMVD). LMVD quantification is much more challenging than blood vessel density because of the natural heterogeneous distribution of lymphatic vessels. In contrast to blood vessels, lymphatic vessels also support spread of metastatic cells but not tumor cell proliferation and expansion of the tumor mass. Therefore, subtle increases in LMVD might be missed in tumor sections set aside for immunohistochemical analysis although they might suffice for tumor dissemination in a patient. A consensus seems to exist that increased density of peritumoral lymphatic vessels might be sufficient for tumor cell transit to LN even in the absence of intratumoral lymphatics.[11]

Another aspect which has gained attention is the presence of LVI in the tumor periphery. LVI encompassing both types of vessels, i.e., lymphatic and blood vessels has long been recognized as a poor prognostic indicator.[13] However, early studies did not distinguish between the two due to the absence of specific lymphatic markers. The emergence of specific lymphatic markers, such as LYVE-1,[14] podoplanin/D2-40[15],[16] and Prox,[17] has enabled clear distinction between lymphatic vessel invasion (LI) and blood vessel invasion (BVI). The preferential spread of tumor cells through lymphatic vessels might stem from the high frequency of LI in BC as compared with BVI.[12] In patients with clinically staged I and II breast tumors, LN status is one of the most important prognostic factors for survival independent of tumor size, histological grade, and other clinicopathological parameters.[18],[19]

Strong associations have been found among tumor-induced lymphangiogenesis, LVI, regional lymphatic spread, distant metastasis, and survival. Therefore, inhibition of tumor lymphatic vessels appears to be an attractive target to prevent metastasis to LNs.[12]

Our objectives of the study, therefore, were (a) to estimate lymphangiogenesis using D2-40 monoclonal antibody as a specific marker of lymphatic endothelium, (b) to correlate lymphangiogenesis with LI and axillary LN status, and (c) to compare LMVD with T and N stages and grade of tumor.


   Materials and Methods Top


  1. Study population: Fifty consecutive cases of IDC breast who underwent modified radical mastectomy (MRM) at our institute from January 2009 to March 2011 were studied. Archival data and paraffin blocks were retrieved
  2. Inclusion criteria: The cases were included both genders, any age, and any tumor, node, and metastasis status
  3. Exclusion criteria: Noncarcinomatous malignancies of the breast, for example, sarcoma, lymphoma, melanoma, recurrent carcinoma(s) breast, metastatic tumors to the breast, and patients of carcinoma breast where axillary LN dissection was not carried out as a part of surgical procedure were excluded from the study


  4. MRM specimens were dissected as per standard protocol. Tissues were formalin fixed and paraffin embedded. H- and E-stained slides from all the blocks of the tumor were reviewed, and the section showing tumor with adjacent normal breast parenchyma was selected. Immunohistochemistry (IHC) using D2-40 to stain lymphatic endothelium was carried out on all cases using standard protocol [20]

  5. Assessment of LMVD: Immunostained tumor sections were scanned at low magnification (×10 ocular and × 10 objective), and the three most vascularized areas in the peritumoral areas (hot spots) were chosen. Peritumoral lymph vessels were defined as D2-40-positive vessels located in preexisting mammary stroma within a maximal distance of 2 mm from the tumor periphery. The LMVD was calculated by counting the number of lymphatic channels stained by D2-40 antibody in three hot spots. An average of the three counts was taken as the LMVD for the case.


This study has the approval of the ethics committee of the institution.

Statistical analysis

Statistical analysis was done using SPSS software version 14.0 for Windows (IBM Corporation, New York, USA. (a) Pearson's correlation, (b) Chi-square test, and (c) Mann–Whitney U-test were used. For analyzing associations between categorical variables (e.g., presence of LI and presence of LN metastases), Chi-square test was used. Where the data were not normally distributed, nonparametric test, i.e., Mann–Whitney U-test was used to compare independent variables. P<0.05 was considered statistically significant.

All the 50 consecutive cases of IDC breast were female patients. The youngest patient was 30 years of age, and the oldest patient was 72 years of age (mean age 52.7 years). The peak incidence of IDC was seen in the 51–60 year age group. All the tumors were histomorphologically IDC (not otherwise specified [NOS]) [Figure 1]a.

All cases showed the presence of lymphatic channels both in the intratumoral and peritumoral areas. All of these lymphatic channels stained with D2-40 monoclonal antibody, a specific stain of lymphatic endothelium. As no false positives were seen, immunostaining for D2-40 showed a high specificity and positive predictive values. LMVD varied from 0 to 58 with mean LMVD of 11. LMVD of 0 was seen in 5 cases (3 of these 5 cases had positive LNs).

The cases were regrouped further into two groups each according to their T and N stages and grade of the tumor for ease of statistical evaluation. Patients with T stages 1 and 2 were grouped together and those with stages T3 and T4 were combined as the second group. Similarly, N0 and N1 were combined into Group 1 and N2 and N3 as Group 2. Tumors of Grade 1 and 2 were put together into one group, and Grade 3 tumors were kept separate in another group. The mean for LMVD was higher in cases with higher T stages (T3 and T4). However, this was not significant statistically. The median for higher T stages was 10.67 with Mann–Whitney U-test statistics 243 and a P = 0.846.

The mean LMVD was 17.2 in cases with higher N stages (N2 and N3) as compared to 8.76 for lower N stages (N0 and N1). The median for higher N stages was 14.56, with Mann–Whitney U-test statistics 152.5 and a significant P = 0.013. Therefore, higher N stages had statistically significant higher LMVD. The mean LMVD was higher in cases with higher grade of tumor (Grade 3) but was not statistically significant. The median for higher grade tumors was 11.67, with Mann–Whitney U-test statistics 211 and a P = 0.375.

LVIs were assessed in the peritumoral area only [Figure 1]b. About 55.3% of cases with LVI on H and E stained positively for D2-40 antibody [Figure 1]c, thereby indicating that the tumor embolus was actually within a lymph vessel, i. e., LI. The mean LMVD in cases with LI was higher than in cases with no LIs. However, this was not statistically significant. The median for cases with LIs was 9.33, with Mann–Whitney U-test statistics 297 and P = 0.883. Patients with positive LNs had a higher mean LMVD, but this was not statistically significant. The median LMVD in positive LNs was 10.33, with Mann–Whitney U-test statistics 231.5 and P = 0.399. The correlation of all clinicopathological parameters with D2-40 immunostaining is shown in [Table 1].

D2-40 also stained the myoepithelial cells (MEC); however, the staining pattern was different. The MECs stained less intense with an irregular staining pattern as compared to lymphatic endothelium. The antibody also stained few tumor emboli which completely filled the lymph vessel as shown in [Figure 1]d. One case where a perineural invasion on H and E was misdiagnosed as stromal invasion stood out as LI after D2-40 immunostaining [Figure 1]e.


   Discussion Top


IDC is the most common morphological variant seen amid BCs. Our study included 50 consecutive cases of BCs, all of which were IDC (NOS) breast. BC is one of the leading causes of death in women between the ages of 35–60 years.[21] The mean age of 52.7 years was seen in our study. BCs have a female predominance and are rare in males as seen in the epidemiological study carried out by Yeole and Kurkure,[21] where it was seen that BC is about hundred times more common among women than among men. All 50 cases included in this study were females.

D2-40 monoclonal antibody is a specific and preferred immunostain for lymphatic endothelium.[16],[22] The intratumoral and peritumoral lymphatic vessels in all our cases stained positively for D2-40 antibody. Therefore, D2-40 had 100% specificity in our study. This compares favorably with the study by Kahn and Marks [16] who also found D2-40 to be highly specific and sensitive. LVIs were studied at the peritumoral areas denoting the malignant front of tumor and also because the lymphatics are more in the peritumoral area, as seen in other studies.[10],[13],[23],[24]

Lymphangiogenesis is present in BC patients as was seen in our study. Several other studies have also brought out this fact.[7],[25] However, Boneberg et al.[8] in their study contradicted this by saying that primary BCs are not a site of highly active angiogenesis and lymphangiogenesis. There have been studies showing association of lymphangiogenesis with LN metastases.[10],[12],[26] Lymphangiogenesis is also seen to be increased in cases of triple-negative BC.[27] It has also been associated with extensive lymphatic spread of inflammatory BC.[28] It has also been seen that inhibiting human epidermal growth factor receptor 2/neu reduces lymphogenic metastasis.[29]

In our study, lymphangiogenesis was significantly associated with higher N stages. This is in concordance with the study conducted by Kandemir et al. as well as Ansari et al.[30],[31] Kandemir et al. had also found a significant correlation between lymphangiogenesis and higher T stages, LI and LN status, and Ansari et al. had, in addition, found significance while correlating it with the grade of tumor. Our study also showed a similar trend though we did not find any statistical significance. This may be attributed to the small sample size of only 50 cases. Further studies comprising larger study population are warranted to statistically confirm the fact. An important aspect of detecting lymphangiogenesis is the concept of targeted therapy. Studies have shown that targeted therapy may be beneficial in preventing metastasis and combat advanced cancer.[32]


   Conclusion Top


Our study shows D2-40 monoclonal antibody to be a specific immunostain for lymphatic endothelium and helps detect LIs. Lymphangiogenesis is seen in IDC breast, and although LMVD increased as T stage and grade increased, it was not statistically significant. Detection of lymphangiogenesis may be a potential for targeted therapy as our study shows that LMVD increased significantly with higher N stages.
