    Hi aida71! I've been searching for someone who shares the same diagnoses. I'm 45 and was just diagnosed with mucinous carcinoma. I'm struggling with with plan of treatment to move forward with. It would be great to connect with you

    I am recently diagnosed at age 45 and I've been reading this thread. Thank you all for the wealth of information and encouragement.

    I'm still not sure exactly what I have. The initial biopsy pathology report says mucinous carcinoma. The follow up lumpectomy path report downgrades (or upgrades depending on perspective) to invasive mammary carcinoma with mucinous features. My 2nd opinion on the lump slides says IDC with mucinous and micropapillary features. It also says the positive node has predominant micropapillary features. It's clear to me that the cancer is definitely mixed. What I don't know is the % of mucinous vs micropapillary. My OncoType results are not back yet.

    I have some questions and hope for some feedback.

    1. Should I ask for a 3rd opinion on the pathology or proceed with the treatment plan for the most aggressive component which is the micropapillary?

    2. The lump path doesn't retest ER/PR/HER2. It merely references the # from the biopsy path. Is it necessary to request a retest based on the lumpectomy? If so, should I ask them to retest the tumor (more mucinous) or the node (more micropapillary), or both?

    3. The tissues/slides sent for the OncoType only contain the tumors, not the node. Again, with the node have the more aggressive subtype, should I ask for an OncoType on the node itself?

    My concern is being under diagnosed. Since the biopsy path labels it mucinous carcinoma, I've been hanging on to the good prognosis of a pure MC. I worry about making decisions on chemo/rad/hormone based on incomplete info or being too optimistic.

    I have a real hard time finding information on BC with both mucinous and micropapillary features. Both subtypes are rare in its pure form. One has really great prognosis while the other has an unreasonably high mortality rate. It's really difficult to reconcile them in my head.

    Miraloma, a warm Welcome to you, even though you'd probably rather be somewhere else. Yes, we're some oddball mixed dx's with mixed variants, just to keep it diverse for our medical teams.
    Yes, you appear to be following our diversity. I'm another mixed bag with mixed mucinous and invasive solid papillary carcinoma, a sister diagnosis to some of what you've described. Researchers previously associated papillary variants as precursors to colloid carcinoma, aka mucinous carcinoma.

    Yes, yes! You will thank yourself later to obtain 2nd, 3rd & 4th opinions on the surgical pathology. ( I did & each was different.). NCI Cancer Centers with dedicated breast pathologists are best. Smaller institutions don't see enough of us to know enough, and everyone is trained differently.

    Oncotype DX (GenomicHealth.com) is an assay you might wish to check with your insurance about regarding pre-authorization so you'll be ready following surgery.

    If you read through this thread, I promise you won't be bored, with the wealth of info and informative links and references. It's a steep learning curve for most.

    I'll check my old files, and I'll private message you some links which might include your interesting diagnoses.

    Great questions...


    Above is a most recent link to micropapillary bc.


    Regarding additional pathology testing...I wholeheartedly agree that you should get another pathology opinion. You might wish to contact the rare breast cancer lab at Sloan Kettering.


    https://www.mskcc.org/cancer-care/doctors/jorge-re...



    That said, the standard of care requires that you treat the most aggressive component of the tumor. So, once the pathology is conclusively evaluated, your treatment plan will be confirmed.


    Keep us posted! We are here for you!

    WeAreConnected and VoraciousReader, thank you for your feedback.

    My 2nd opinion pathology comes from an NCI designated center. There's another NCI center near me, which where I am considering sending my slides for a 3rd opinion. What's stopping me though is timing. My surgeon's putting my case in front of the tumor board next week. I can't send my slides out till that's done. By then, I'll be 7 weeks out from surgery. Having a 3rd/4th opinion may give me more info, but it will also delay the start of my treatment. If I were pure mucinous, I'd feel ok to wait. This micropapillary business really scares me.

    Big sigh of relief! My OncoType score is 12 and the oncologist does not recommend chemo. On to radiation I go! Can one really be excited about getting radiation?!

    Thank you all for your encouragement and support. I could not have gone through the last few months without y'all. Stay strong, sisters!

    First welcome to us MC sisters I am so glad that those like Voracious reader can answer your complicated questions. Yes you can be excited about getting radiation if as the research indicates that it deals with you not getting a recurrence of the breast cancer. I made my treatment as exciting as possible. I booked in the earliest appointments in the day that I could get into so it was over & done with before it ate up a chunk of my day, also you get less system or patient holdups then. Of course early appts are not always possible. I drank heaps of water daily used all of the creams they gave me & got no radiation burn even with my English sensitive skin. I treated myself to a special coffee each day after the session, so reward yourself somehow each day. A friend of mine bought a pile of scatchie tickets (the win a prize type) for the radiation treatment series and used one each day for her reward & won a prize! My oncologist was quite strict about me walking after the session for an hour each day, in the fresh air, for my body to recover from the "radiation blast". I managed the radiation really well and if I had to do it again tomorrow I would happily participate.I am really fit & well 6yrs 4mths after diagnosis. Lots of prayers & blessings

    Just when I thought I was out, they pull me back in!

    I got a low score on the OncoType but apparently I'm still not ready for radiation...

    I had 2 small tumors (13 mm, 10mm) in close proximity to each other. During my lumpectomy, 1 enlarged lymph node (18 mm) was removed, which turned out to be positive. My dr ordered the OncoType on the large tumor (with mucinous features), which came back low risk. Subsequently, the 2nd opinion pathology report said the small tumor was more aggressive (with micropapillary features.) The lymph node, which was bigger than the tumors had solid mass, was predominantly micropapillary, i.e. much more aggressive than the tumors themselves. The tumors and the node were ER+, PR+ and HER2-. Ki-67 was 15% on both tumors, but >30% on the node, consistent with aggressiveness.

    A tumor board suggested OncoType on the lymph node but Genomic Health said OncoType was not validated for node tissues. As a compromise, my dr ordered a OncoType on the more aggressive tumor. I'm waiting for the result.

    Given that the mass in the node is much more aggressive, I'd like to know:
    1. Is there a genomic test that is validated for node tissues?
    2. Are there any other tests, markers or indicators to perform on the node to evaluate the need for chemo?
    3. Does it make sense to start hormone therapy while I wait for test results? I'm 45 years old and had the lumpectomy over 2 months ago. I'm concerned about the delay of treatment.

    Thank you in advance for any feedback and suggestions.

    There are chemo related integration medicine threads you can also check. Look into individualized chemo-sensitivity assay.

    You're in California, which has several chemosensitivity labs. Usually these labs require solid tumor biopsy tissues, but if you speak to cell biologists, they can perhaps lead you in the right direction regarding your node.

    Why would a protΓ©gΓ© be more aggressive than its parent tumor? Just curious. Good luck.

    What a terrible place to need...yet, so wonderful to find it. I've spent the last week plus reading & learning a lingo I never wanted to learn. Just as you all before me.

    I was recently diagnosed with " intraductal & invasive Papillary Carcinoma with FOCI of invasive mucinous carcinoma". Lymphovascular invasion is present. ER/PR + HER2 neg (1+). Grade 2. Biopsy: 8.5 cm, margins not clear.

    I, like many others on here, had fibrostic tumors and very dense breasts which made mammograms kind of useless. I injured my left breast in May of 15' by running into a sharp object...when I noticed slight bleeding from the nipple I didn't worry too much about it...however, I did go to my PC Dr. and he recommended an ultra sound...I finally did it because it never healed...it didn't bleed all the time, it seemed to come and go, including the lump that I assumed was just another fibrostic tumor. Anyhow, here I am!

    Feeling very optimistic and ready to beat this! Dr. told me it's considered Stage IIIA because of the size and lymph node (1) involvement.

    I start AC April 6th.

    Utih, a warm welcome to this wonderful community of brave sisters. I hope you are recovering from your surgery. Your exotic dx is amazingly similar to mine, except tumor size. It's interesting my medical team had staged me only according to the actual size of total invasion (multi-focal). Like you, I also had suffered a sharp injury prior to dx in the affected area.....very coincidental.

    Can we assume the Oncotype Dx test from GenomicHealth indicated chemo treatment? Did your pathology state whether your mucinous invasion was mixed mucinous or pure mucinous carcinoma?

    Nice to have you here with us.... healing hugs!

    WeAreConnected...thank you so much for the warm welcome.

    That is a very strange 'coincidence'! It is not 'pure' mucinous as far as I can tell...I'm still learning this.

    I start AC chemo on April 6th (port & node aspiration on 4th), 4 treatments then 4 of Taxel...then mastectomy and rads.

    I had a PET scan last week and it is contained to the breast...what a long, scary process.

    Yes, it's a very steep learning curve, especially when you're hit with 2 rarer cancer subtypes. I'm sorry that you're having to go thru such a complicated process.

    For both invasive papillary & invasive mucinous, the consensus on this board is that 2nd opinions are suggested and warranted on the pathology. With your complicated diagnosis, I would also seek multiple opinions from oncology regarding your treatment plan. A MRI (both breasts) is also suggested prior to final surgery to rule out any occult BC lesions, even though some lesions under 5mm are not always visible in imaging.

    If your tumors are highly ER+/PR+ with papillary, it's a pretty good bet that you would score low on Oncotype Dx testing. There are medical studies which show 8-9 score as being average for papillary and in the teens for mucinous, however it varies based upon the invasive components. For example, if your papillary tumor had conventional IDC (nos- not otherwise specified) adjacent to the periphery of the papillary capsule or embedded or entrapped within the wall of the papillary capsule. Low Oncotype Dx scoring is usually indicative of little benefit from chemotherapy, as you may or may not realize.

    Your low HER2 negative (1+) is also exactly what mine had shown. My papillary tumor was almost 3 cm and the mucinous invasions ranged in size from 4mm up to 8mm, but there was a bunch of multiple mucinous invasion with tiny patches of IDC present, thus giving me a mixed mucinous presentation. The BMX had also revealed mucinous occult lesions. Mitosis was high.

    The (4) breast pathologists never agreed on my varied invasive components, but all 4 had agreed on papillary, but had also differed on the variant of papillary (encapsulated vs intracystic vs intraductal vs solid papillary) and the stage/grading. None of the oncologists I had consulted with had suggested chemo, in fact they recommended against chemo. 2 recommended mastectomy and 1 suggested lumpectomy, but I actually had both surgeries, in addition to excisional biopsies.

    Please rest well and wishes for healing!

    Thank you so much for all the amazing information, WeAreConnected!

    My biggest problem is where I live...in the Four Corners Region, Utah...I'm driving to Durango Co which is 145 miles away, otherwise, there's a center in Farmington NM (140 miles), Grand Junction (240) and Salt Lake (360)...the oncologist I'm seeing is a temp out of Portland so he'll be gone this week & I'll have a one who is also new to the center.

    I feel ok with what they're planning...but, I admittedly don't know very much about any of it. The surgeon who did the biopsy is a survivor of bone cancer and I feel that I'm in pretty good hands where he sent me...I don't know. He won't be part of the future surgeries because he's from a different hospital and I want to just pick one place to go! He told me there are 3 different cancers...hence, the chemo?

    Hello All,

    I am cross posting this over from the general CHEMOTHERAPY thread and hope there is no issue with forum regulations/rules. I plan to read all 61 pages in the meantime. Thanks in advance and thanks in general for everyone's contributions to this forum.

    Would appreciate feedback on when tumor shrinkage became evident during chemotherapy? Immediately, halfway, towards the end or NO SHRINKAGE? Specifics would help in regards to type of chemo and tumor size.

    My wife started A/C + Taxol chemo in December. Doctor skipped the 4th and final A/C after no evidence in shrinkage via mammogram and ultrasound. She moved on to Taxol and has just completed the 5th infusion of 12. At 3rd infusion, doctor believed there was slight shrinkage by touch. Now after 5th, doctor believes tumor hasn't shrunk more.

    As you can imagine, the thought of chemo NOT being effective and melting the tumor is incredibly distressing and her spirits are incredibly low.

    Does chemo flat out NOT work in some cases?

    The differences in the histological types of breast cancer and the response to neoadjuvant chemotherapy: the relationship between the outcome and the clinicopathological characteristics.

    Abstract

    Although effective regimens have been established for invasive ductal carcinoma-not otherwise specified (IDC), the efficacy and prognosis of other minor types of breast cancer are unknown because of their rareness. The clinicopathological features and prognosis of other minor types concerning the response to neoadjuvant chemotherapy (NAC) were evaluated in this study. A total of 562 patients were classified according to the Japanese and the World Health Organization (WHO) classifications, and the number of IDC and other special types (SP) was 500 and 62. The SP patients had a significantly poorer clinicopathological response to NAC and less breast-conservative therapy than those with IDC. According to the WHO classification, mucinouscarcinoma, metaplastic carcinomas and apocrine carcinoma also responded poorly, and patients with metaplastic carcinomas and invasive lobular carcinoma had a significantly poorer prognosis. Despite the poor response to chemotherapy, patients with mucinous carcinoma and apocrine carcinoma had a good prognosis. The response to NAC and the prognosis vary for each histological type. For some types, the prognosis was not related to the clinicopathological response to NAC.

    BACKGROUND:

    In the treatment of breast cancer, neoadjuvant chemotherapy (NAC) has become the standard treatment modality for downstaging purposes. Although effective regimens have been established for the treatment of invasive ductal carcinoma-not otherwise specified (IDC), the data about the efficacy and prognosis for patients with other minor types of breast cancer are insufficient because of the rareness of these tumors. Defining the relationship between each histological type and the clinicopathological response to NAC is essential to optimizing individualized treatment.

    METHODS:

    We retrospectively evaluated the clinicopathological features and classification of the histological types based on the Japanese and the World Health Organization (WHO) classifications before and after NAC in 562 patients with primary breast cancer who underwent curative treatment after NAC between 1998 and 2008. The prognosis was estimated for each histological type.

    RESULTS:

    Of the 562 patients, the number of cases of IDC and other special types (SP) was 500 and 62. In the SP group, the clinicopathological response to NAC was significantly poorer, and the patients underwent breast-conservative therapy less frequently than did the IDC patients. According to the WHO classification, mucinouscarcinoma, metaplastic carcinomas and apocrine carcinoma responded poorly to NAC. The disease-free survival and overall survival were significantly worse for patients with metaplastic carcinomas (p<0.001 and p<0.001) and with invasive lobular carcinoma (p=0.03 and p<0.001) than other cancers. Despite their poor response to treatment, patients with mucinous carcinoma and apocrine carcinoma had a good prognosis.

    CONCLUSIONS:

    The response to standardized NAC and prognosis varies for each histological type. For some types, the prognosis was not associated with the clinicopathological response to NAC. Innovative regimens should therefore be investigated for each histological type to achieve the best response.

    And your final words!

    She is doing chemo to chase a "stray node" in an inoperable location between her ribs. Seven more chemo days remaining... 6 after today.

    So very sorry, Orawan, but unfortunately it's not a one-size-fits-all scenario, as you shall see from the snips I'm sending you with a PM (private message), since much of it is off-topic for this thread, if that's OK?

    Mammogram, sonogram & MRI occult mucinous carcinomas tumors are not infrequent. Patients with multi-focal tumors tend to have more aggressive tumors & not always do as well as others, plus circulating tumor cells, especially clusters, can be present in our bloodstreams long before tumors develop. The microscopic & prognostic presentations can vary from lesion to lesion, whereby the quantity % of cellular structure differs. Also the mucin to cell ratio and the argyrophilic granule content at presentation. Small scant amounts of mucin, big nuclei, irregular nuclear outlines presence of nucleoli, if found, usually point to more aggressive mucinous BC also.

    Additionally, our specific BC subtypes with our own different variants, our lifestyles and our genes are not all taken into consideration by the medical establishment in treatments, trials & studies. Medicine is imperfect. Wishing you the best, prayers & hugs!

    Which molecular subtype of mucinous carcinoma is it?

    Hello,

    I am unfortunately joining the MC club. First of all, wanted to say a big thank you to Voracious Reader for all the previous info in this topic, it's provided some incredibly helpful background info. I've now devoured all 61 pages!

    I find myself somewhat atypical in my MC presentation. I am 31 and have a poorly differentiated high grade MC, which I understand is aggressive. My diagnosis comes after a pregnancy and directly after 17 months of breastfeeding. I also got two benign ultrasound results and a clear mammogram before DX, the cancer was picked up only by biopsy.

    Last week I had a double mastectomy and was incredibly relieved to get the news that my sentinel nodes have come back clear and with clear margins on the dmx. My path report refers to to mucinous carcinoma but gives me no clues as to whether this is pure MC composition.

    I'm waiting on on oncotype results but given my age, high grade (3), and Ki-67 score of 17%, plus the multifocal invasive tumours (8 of them!) and 70mm of surrounding high grade DCIS, I imagine chemo is likely to be recommended unless the oncotype score is extremely low. We also have a strong family history of breast cancer but I have tested as BRACA negative.

    I'd be very pleased to hear from anyone with similar cancer makeup (high grade, multifocal, Er\pr+++, her-) and what treatment you opted for.
